Honda Foreman 450 ES | Broken Rear End Diagnosis and Disassembly - Rear Wheels Not Driving

- čas přidán 15. 03. 2022
- This is the second time I have diagnosed and fixed this type of problem on late 90's Foreman's. The first was my 1996 Foreman 400 which gave up because of a frozen drum brake and now this Foreman 450ES which got into mud hole and the rear axle gave up.
While i do not have much experience beyond the three foremen we own i would imagine that this type of issue will start to rear it's head at all of these bikes continue to age. It is the first real issue we have ever had with them and they are still the toughest best bike i have ever seen.
While this needs to be independently check i believe these parts are interchangeable with most 90's to early 00's Foreman's with a straight rear Axle.
Good Luck!

Best Foreman repair video ever!
Thanks dude!!! Greatings from Bolivia
That’s pretty awesome that you have a 1999 4 Wheeler since 1997
I have a 2001 350 and that's my exact problem. Just waiting on parts to reassemble!
Nice looking wheeler, definitely worth fixing
Hey there, This was so so helpful, and I would agree that putting the small output shaft back in place is not that easy. But I did find a easy way to do it and it takes no time at all. Undo the clamp on the boot ( the large one at the back ) and leave it off. Then undo the swing arm pin on the left side of the bike only ( the side where the axle goes through). This will allow you to move the swing arm around more and you can pull the whole U-Joint assembly out of that section. put the shaft back in after greasing it and then slide the axle back down the tube starting from the engine side. Now it does help to have someone with you to make sure it does not slide out the other end during all the movement getting it back in but you can do this on your own as well, just take your time. Now slide the u-joint coupling back on the engine splines and re align the swing arm and place the pin back in and tighten it up to torque specs. There, now put the boot and clamp back on and your out put shaft is back in and ready to hook up. Hope this helps as well.
great video! thanks
Great vid man.
I did the axle on our bike we leave at our hunt camp. I lucked out and since I knew in the fall I would be doing the job in the spring I left the parts in my Amazon cart all winter watching for price swings. I picked up an entire rear diff for $200CAD instead of the ring gear+seals. Was onsale plus a $25 coupon or something along those lines.
eBay I was able to get a new axle for $125.
Then just bearings and seals off Fortnine.
Lol the rear drum stops working as soon as you drive it away from the dealership. I went on a mission sealing it and replacing the cable on my own 500. Worked excellent for about the first 20 minutes of the next trail ride lol. And the cable/mechanical disc brake conversions don't work much better and certainly not for the price. Haven't seen an hydraulic conversion kits but I'd imagine they are 2x the price of the mechanical
Awh man, EXCELLENT TACTIC letting them sit in your cart. Nice work.
I don’t have much experience with the rear disc conversation and was debating it but based on your review it’s a pass for me. My brothers 450ES has the hydraulic discs of front and holy shit do they work. I say that but I have been riding a bike with no brakes for like 15 years lol
My understanding of the front conversion is you need to increase rim size which I’m not a super fan of cause I just got new tires. May try them with a .5” spacer and see if that works.
I just bought a 1998 Honda Foreman 450 this past weekend. It has the front and rear disk brake conversion and runs great....BUT! this issue just happened (or it was already an issue and I didn't realize it when buying it) either way, this video is going to help a lot. Seems like a great machine otherwise. Thanks for making this video eh.
If you already have the disk brake conversion hopefully that makes life easier. Based on it’s age it was due for this to happen lol. While you are tearing it apart you might as well do all the seals and bearings. All balls sells a complete kit and isn't super expensive. The link is in my other Foreman rear end assembly video
had foremans for last 25 years still have 3. , all my brakes work perfect like new , ya just got to keep and eye on them ,maintain them keep them adjusted etc pull 10 mm drain plug in backing plate every oil change at a minimum or more often if yer in deep water a lot , if any water comes out replace yer seals , if a seal goes replace it it doesn't cost nothing ....penneys , , they are simple , the rear brakes on my 98 450 have never been apart and still work perfect 10,000 km I tap grease nipples into foot lever pivot and rear cam pivot in backing plate , they will last forever because them two points are first things to seise and then intern cause yer cables to seize etc ..... then ya got a pile of shit brake problems and everyone starts yelling Honda brakes suck lol. but they really don't . I can guarantee there will be no axle issues if brakes and seals are maintained as that issue is a direct cause of corrosion eating the splines and deteriorating them to the point of failure
buddy has a new can am had to do brake pads already at 1300 km lol cost him a fortune , all my foremans have a combined km of 23 000 km and never replaced a pad or shoe yet lol all original and work perfect
No doubt maintenance would help make the brakes last. Unfortunately routine maintenance wasn’t a thing for us until I started doing it all. This 450 was bought new when I was 8 years old and my 400 was bought when I was 5 lol
Every now and then you will get lucky and not have to replace the ring gear, I’ve replaced many axels and never had to replace the ring gear, they make the ring gear harder then the axel.
Wow, this video is excellent, honestly how every how to video should be shot. Very informative and great camera angles! Quick question, is there any reason why you can’t attempt this with the swingarm still attached
Thanks for the feedback! So I have done this twice and both times yanked the arm off. I believe you could complete it with the arm still attached but you would need to remove both hubs, drum brake and axel tube on the brake side. Personally, for the few extra bolts it’s so much nicer to work on the axle when it’s in a bench VS hunched over working near the ground. Good luck!
Could you do me a huge favor if you have the old worn out Axel I need to know the diameter of it is it 1" the very center where the hitch goes
Awh man i'm sorry. All the axles are long gone. The one from the 400 got tossed and i believe the one from the 450 is also gone.
can you change that back axel without taking the back end off?
I believe you could, however if you experience this failure you will need a new ring gear as the splines that connect to the axle will also be smoked. I think technically you could do it without fully removing the rear swing arm but you would be damn close. I did this on both bikes because i couldn't take the whole bike with me and it was easier to put that on the bench vs. rolling around on the ground.
If ur just replacing the axel u can. But if your replacing ring gear it will have to come off as shown in this video.. great video I'm unfortunately gona have to do this to my 04 450.
