Great Mod, I'm going to try it out on the Upper Triangle Control Arm on my WJ for lifting it. Thanks for the video. Keep spreading the knowledge.
Looks good Martin! I bet it rides 1000% better!
great job Martin,first class work my friend.
Many thanks
awesome as always, the front will be sweet
bravo
Thank you, yes I'm looking forward to get the front arms done.
Martin you are amazing!!! Thank you for ALL your knowledge and experience. I enjoy watching your videos and you have helped out a ton on my wj. God bless you sir and thanks again.
You are very welcome, I appreciate that, thank you.
Here here
Great video as usual! Waiting for a good solution you come up with for the front ones :)
Also would love to see a video on an building a one-ton steering for the WJ like you did for your xj ;)
Crazy good job good sir , This is something I got to do . I have a lift on this wj when I bought the guy really cheaper out and I've been replacing the needed parts . I picked up some upper extendable control arms for the front but this is something I want to do and the fact you have an over size sway bar in the back is something I've also noticed I need to do .
Thank you, glad I could help
Nice setup from ballistic fabrication
Yes indeed, thank you
Good call!
I love your introduction to your videos. I especially like that custom plate in the back the reads ‘Illfixit
Thank you, yes that plate came off a Ford Dually I used to have. I had a handyman business back in the day.
Nice engineering on the fly at the yard. talent martin. Welding machine runs great by the sound of it.
Thanks, Greg, yeah the Miller does a great job.
Man that’s awesome Martin - I’m lifting my WK and was going to purchase new adjustable arms for the rear to centre the wheel ........I’ll do this mod instead. Awesome work......liked and subscribed🤘🤘
Glad you you found this video helpful, thank you for 👍 and subscribing. 🙂
Thanks for the info!!! I’m going to do this to my lifted off-road XK
Glad you found it helpful!
Great job as usual.
I appreciate that. Thank you! Cheers!
That turned out great 👍
Thank you! Cheers!
Nice idea on customizing the arms
Glad you like them!
Love the video. Then I said ikes when I saw that lower grease fittings face down and forward. It's all good as long as your not thumping over logs and rocks and mud.
Thank you, my Grand is Mall Rated...Lol, No lugs or rocks in the future.
You can just rotate the joint 180* and the grease zerk would be facing up.
Well done. Not just the modification. But also recognizing the WK arms are a no brainer. Please let us know more about how this mod has improved driveability, handling etc.
will do, thank you
Looks great nice joints
Thanks 👍
Nice burn out 🤩
Yes it was, Thanks 👍
looks great! i have to replace mine. cant believe how clean the underside is on your jeep! my 04 oveland been in wisconsin all its life and is a bit rusty underneath...thanks for the video
Thank you. Yep I know all too well about the rust I used to live in Iowa. I don't miss it.
Hello there, always good videos .....
Glad you like them!
Nice job Martin.I have some coil spring buckets for a Dana 30 that I bought from Ballistic Fab.They make some really nice stuff.Barnes 4x4 is also a great place to buy this stuff too....
Thank you Dan and thanks for the info
Great job keep it up
Thank you!
I love the work and thought you put into each video. If you could place the part number in would help me greatly as I will be doing this mod on my 01 WJ as well. Great job man take care...
Here are the part numbers of the Ballistic Fabrication 3.0 POLY BUSHING (BUS-663-23)
7/8 IN SQUARE TUBE ADAPTER (TA-290-1)
and JAM NUT (JAM-711)
Oh man! This is sweet! The WJ shimmies when I give it , and let off gas. Gonna have to do my rear LCAs. Have you considered selling a set? Id buy!! I really enjoyed the "other martin" poppin in and correcting you 🤣. Hilarious
Thanks Dan, I know you got the skills to built a set. Glad you like the other Martin, he's got my back.
@@martinbuilt thanks buddy! But if I build my own they'll just be lame ol Danbuilt 🤣
I spent most of my adult life in southern Nevada and 10 of them in Pahrump. I miss rust free!
I love the rust free vehicles, another reason I don't miss Iowa. I might move to Pahrump when I retiree
@@martinbuilt I'm in Chicago suburbs. I wish I was back there in Nevada.
Sweet! I bought some rough country fixed control arms and I was wondering if I can convert them to adjustable. I found the perfect vid.
Right on, glad you found it helpful 👍
Those are so awesome! U should patent that for sure!
Thank you, Kimberly
Yeahhh nice idea
Thankyou. 😎
@@martinbuilt hello i have a problem with my grand cherokee 2002 when i accelerate the jeep go to the left and i release the pedal it goes to the other side. i noticed that my spring coils are weakened can you be the cause?
Nice work man. you do know u can just buy them arms already made and just bolt in
Hey Martin, on your ground clamp, like mine you have a slightly longer bolt holding the contact on the inside of the jaws. On my Mig and Tig i found that i had to reposition my work far far more than stick welding (due to the way the torch handles) so i added a large round rare earth magnate to that outside part of my ground clamp and just slap it on either the vice or my work. My bench has a 12 gauge steel cover and the vice mounted to that, I'll often just leave the mag on the table top and weld fine, saves me a lot of time.
yea, I which I never sold my welding table but I didn't have the room in this garage.
That's a funny quadra drive system you got there it only sends power to the rear tires 😂 Great mod and how to video 👍
Lots of guys swap t cases. I've wanted to do it but i am short of funds.
@@LectricLetus mine swapped itself 😂 It only works in 4 low so I can burn the rears too .
@@jaysmith5084 uh, yeah that's not how its supposed to work. 4 low is supposed to keep youn in low gear. At least from what i know about the quadra drive.
@@LectricLetus yes I think something in the t case is broken
Hey Martin do u have a video on the installation of those suspension straps? And what exactly do they do?
I don't have a video for those. They are good for a couple reasons, for me it limits the amount of body roll and for off road it stops the suspension from downward traveling instead of the shock limiting the travel, that could cause the shock to fail.
Can I see how you rebuild a starter for a 2003 Dodge Ram 4.7
Martin, WOW. I love your WJ stuff. I have a question that I would like to ask and trust your vast knowledge. I live in the rust belt of northern Ohio and my rear lower control arm front mount has rusted away / torn away from my subframe. Would it cause any geometry problems if I made a longer lower control arms and fastened them to my subframe 12-18" farther forward where it's solid? This is on my 02 WJ 4.7l W/SelectTrac. My favorite of my 4 WJs but it is so rusty, it has become my winter dd. Thanks in advance.
Thank you. I appreciate that, and thank you for watching.
Yeah, I think it would probably change the geometry a little bit as the rear axle goes up-and-down. It is gonna put a little bit of a twist on it, but I would probably still do it.
And you're gonna want to do both sides.
Awesome job. I am definitely going to do that with my WJ. Do you happen to know how far out you can actually extend the joints???
For the 3" of total lift from oem specification, the lower control arms need to be 16.09" long instead of 15.75" to keep the correct geometry.
I am putting a 3" Supreme Suspensions Spacer Lift, Adjustable Track Bar, Bilstien 5100 Shocks, and Brand New OEM Coil Springs with new Isolators.
I was debating on doing front and rear lower control arms as I know it's going to change my pinion angle a bit and didnt want to spend a ton of money from Core 4x4 or somewhere for them.
Thank you Colin, yes the arms can easily be extended beyond 16.09"
@@martinbuilt right on man. Cant wait to see what you do with the front lower arms, I will do both at the same time. Haha
You say your going to do your front arms too. Are you going to use arms from the front of a WK ? I’m stopping by our u pick u save today to find the rear square arms and I’ll look at the front there too. If the WK front arms are square and bent as my original on my WJ I’ll grab the front arms from the WK. I’ve talked to Ballistic Fabs the other day they have everything in stock and plenty of them poli joints, nuts and square adaptors so I can do the same to my WJ. Thanks so much Martinbuilt.
Glad you liked it and hope you enjoy building your control arms. The front of a WK has an independent front susenpsion and does not have those control arms. Haven't got around to building the front ones yet.
You should start mass production of all the stuff you make sir. I would buy it!!!
Thank you, I do appreciate that!
Id want that valve seal tool you made. I halve a valve leak and don't want to pull the heads to replace it.
Howdy, so that's a great fix if you have to change the one end due to a damaged end, but the Alignment person is going to hate you, lol every time you need to make an adjustment, you'll have to remove the bolt and nut, and as a frontend guy, it take sometimes several times of adjustments to put it in spec's, (i would charge you extra) no fun, what really needs to be done is to have a set up like a turn buckle type system, (IE tie rod type adjustment,) any way if you're looking to make your suspension adjustable look into a fully adjustable component,,,cheers
I has a question...Will a HO 4.7 work in a 99 wj straight across swap?
Yes It will.👍 as long as it came from a 02-04 WJ
Do you rember what everything cost ? for the new joint
130
How did you correct the up and down movement in the arm tube ? You never explained that.
Also are those bushing housings the same size as the lowers on a KJ Liberty 06 ? I think it would be awesome to make a set for my Renegade.
The up and down movement? I didn't realize there was a problem.
@@martinbuilt about the 6 minute mark in the video. You fit the adapter into part of the arm tube and there is slack up and down.
Awesome build anyway. I was just wondering about that part because there's no slack when you go to weld them together.
@@justinholland7657 oh I get what you are talking about. Like you said after welding there not going anywhere. Thank you.
I thought the WJ lower control arms were a little over 2” shorter than the WK lower arms?
just a little short than the WJ, lees than an inch
I bet stock JK arms would work also
I'll have to ask my JK friends if they have any laying around
What size wire are you using for you mig
.030
can u make me a pair for the same jeep/WJ 02? if so how much?
sorry, my plate is pretty full
Only to live in the area that’s rust free. A 2004 vehicle in Pa is usually a washing machine by now.
yeah I used to live in Iowa I know what you mean.
I was excited to try this on my 96 zJ but I have no p cutter 😂
a what?
martinbuilt plasma ?
@@rougeone1394 I didn't need a plasma for this project. I used a bandsaw, a saws-all or even a hack saw would have worked.
martinbuilt 10-4 thanks for response may try that method. Keep up the good work brother
