Diff mount bushings...

[06 H3]

I am getting frustrated...My diff mount bushing is out on the driver side and I have two sitting around one driver and one passenger but they are both bad. I wanna replace them with upgraded bushings. Every local place I call that makes custom bushings wont deal with me directly, They want me to go through their distributor...but I dont know who their distributors are. Other companies want orders of 1000 or more. I tried to stay local so I can deal with them directly and hand them my part and have a product back sooner then later. Trail duty wont return my voicemails or emails. Kaleb can you get your guy to make some diff mount bushings? Does anyone have a direct contact to someone who can make me this stuff? Preferably so cal. At this point it can be straight up steel replacing the bushing. I just want the diff to stay put.

If you want it to be solid why don't you see if you can assemble something with bolts, washers, etc? Fill the hole and cover the ends with washers.

Dwaine was playing with this and we couldn't figure out a reasonable way to make a marketable fix, especially considering the relatively low price of these pieces. Granted his wouldn't wear out but they probably wouldn't sell well with the amount of labor required to rebuild them.

Maybe we can talk to Dwaine soon about replacement bushings only if people want to press out their own failed bushings.

lol we are working on it! Just need time unfortunately like with our other projects. We are exploring two different routes, 1) battle with the stock bushings and replace with a poly substitute. 2) We were going to just bend up a new diff bracket out of 5/16" steel and use a piece of 1.25" dom tube with standard poly bushings.

IMO...the bushings need to be rotated 90 degrees. Instead of the bolt going up thru them into the bottom of the frame...you would need to weld on a small mounting pocket on the bottom of the frame to receive the bushings, and then insert the bolt horizontally. Basically just like a small leaf-spring mount. Round bushings work good when the shock load is perpendicular to the bushing bolt. Frankly I've never seen any other diff bushings mounted sideways like the H3's and that's probably why they don't do their job. For instance...take a look at all the other GM diffs (Corvette, GTO, 1500, 2500, etc.). The bushings are always sideways to the load they're trying to control. Not sure why the H3's are mounted like they are.

interesting CJ....Not sure how much work that would take and how much gain it would give.

Alex, If I pulled the bushing out and just welded a washer on top and bottom and ran the bolt through do you think that would give enough support? I may need something in between.

Press the old out find someone with a lathe turn one out of aluminum, if you want to go solid. I would make you some if I was closer or had an extra mount to measure up.
