HOOD SHOCK / HOOD LIFT SUPPORT REPLACEMENT in less than 3 minutes (easy)
zhlédnutí 86Před 3 měsíci
Hood shocks are a common failure point and very annoying to deal with. This process is applicable to almost any vehicles hood or rear hatch lift shocks. These cost about $25 each at my parts store but prices can vary greatly depending on the application. A shop would charge about $25 - $50 for this job.

If you want to do this job, you will likely need a cutting torch, and I recommend a new bolt (which I did not have). If you have a new bolt, you can be more aggressive with the cutting procedure. Good luck!
Nice video! Only one suggestion, use a bearing puller instead of a grinder if you have one.
Hey thanks! Ya I didn't have one and at the time and my acetylene tank for the torches was empty too! Figured this worked anyway because most average Joe's have a grinder.
I can't hear at full volume. No captions either.
Will keep this in mind for future videos, sorry Paul.
Why use a greaseable bearing on the jack shaft when there is no way to grease it ? Older sleds had a way to grease them. They need done every 500-1000 miles. That’s why people have failures with these bearings. I just pop out the seals and clean the old grease out and re pack the bearings. A lot less work ! I’ve done this for years
I didn't realise it was a greaseable until I took it out of the pack, figured it's in a sealed mount so I just sent it in. If it were a customer's sled I would have gone OE but I wanted to ride.
Hi great video Would you be willing to or available to to do this job on my sled. ? 2020 sks Thanks Eric
Hi Eric, thank for the offer but I am a highschool teacher full time and don't have time for sidebusiness anymore.
Nice work! How often should you do a overhaul like this. How do you tell if they are bad before you start. Reason I ask is, I am looking at purchasing 2016 800 Pro S Switchback with 8k on it. Top end was done under warranty. I don't believe the rest of the sled has been touched.
Usually every 3k miles is recommended. Check for any signs of moisture in the chain case, but that's about the only easy tell a seal has failed, which in turn would fail the bearing.
Using a grinder cutoff wheel is the best way to get the bearing off the one end of the jack shaft…??
Depends on the tools at your disposal, you can use a puller and maybe some heat if needed. I didn't have a puller so this was the best way for me.
Puller that has the 3 pins u put into bearing, put plate on with forcing screw and pop off. Amazon has a few different brands
Why not use a puller ?? No chance of damaging the shafts that way
Didn't have one on hand and they usually slip off anyway. I do try them as the first option when available though!
Nice video! Wish I had this a couple years ago. Had the jackshaft bearing go bad after 2,200 miles and just like you said at the 3:00 mark, it messed up the retainer plate too. That was a downer of a day. I'm glad to see a good video on how to do this inspection and work yourself rather than having to have a dealer do all the work.
Glad you liked it, thanks!
Here is another tip and you can take it or leave it ....your call.pack the back side of your seals where the spring is (if they have springs)with grease so when you tap on them the springs stays in place .Simple and it works .
I want to find some spherical bearings like you use for jackshaft and use them for my jackshaft in my matryx chassis.Would you have a part number for your bearings and ill see if they are the size i need for my sled .The oem bearings have no grease hole in them and i want to mod my sled to grease the bearing through the flange
Hi Terry, I don't have the part numbers from this video anymore, but I can recommend checking out Royal distributing or allballs racing online. I like to get the factory number from Polaris.com and cross reference to make sure I get the right ones.
12-1001 with steel seal has the holes in outer race to grease
I hardly ever comment on these videos however this may help you ...get a cheap dremel or jobmate rotory tool and some dremel brand fiberglass reinforced cut of wheels.Not the cheapies that come in the kit .They are nice and small for cutting off the inner race where room is tight .They are probably good for say two inner races each but work nice, easier to control smaller and less heat.Take care.
Thanks for the tip! I usually do use my little diegrinder with a zip wheel for this but I left it at home that day.
@@MR.LARSON92 no problem. Did you do the chain case bearings as a preventative measure ir does it have alot of miles on it .They usually last a long time since they run in the chain oil even though they are sealed the oil gets past the seal and are kinda oil bathed
@terrymunn1224 more preventative, this is my sled and it has a pretty hard life. I have seen the chain case bearing loaded with water from the shaft seals failing in the tunnel though. But I figure may as well replace them all while it's apart.
Good idea@@MR.LARSON92
Great video!! Thanks man. What kind of bearings or kit did you use? OEM or aftermarket?
I use aftermarket, I worked in a dealer for years they're all the same, with the exception of wish.com kind of stuff! I used allballs kits from royal distributing for this job.
throw the bearings in the freezer and they will go right in
Hey thanks a lot great step by step
Glad it helped!
Корявая работа, Съемники есть для таких целей.
I'm assuming you're referring to a bearing puller, you are correct however this gets the job done just as well and the average home owner can do it this way.
Great video, thx
Glad you liked it!
Excellent video. Thank you!
Glad it was helpful!
Very helpful I have a pro ride suspension how do you remove the track off of those
Hi Ron, very similar to this video except you don't have to remove the jackshaft. Depending on the year there may be some slight variations but the general process is the same. Take lots of pictures of every step as you do it it may save you a big headache on re assembly!
extremely valuable information. Thanks!
Thank you!
This is a great video...gives me nightmares back to replacing the PTO side driveshaft bearing on my 2002 Indy last fall. To say that chain case with reverse gears was complex was an understatement!
Those chaincases can be very frustrating!
