Welding Center Diff.......How technical?

[OMN_DSM]

I recently broke my center differential and I'm looking to weld it. I would like to know if I would be ok having a local welding shop weld it up for if I where to point out the places to weld it. I just want to make sure that it isn't to techincal where and how it is welded. Thanks for any info.

if the weld goes through any machined surface such as a bearing mount then you would have to have it remachined. if its just a chunk missing in a non critical area whare the weld will not interfear with any of the componants then it will be fine in ths "as welded" condition.

I would recoment a shop that can TIG weld (GTAW) and not Wire feed (GMAW) Wire feed while fast and fairly strong is not as clean....ie spatter.(the little Metal BB's formed & flying around while welding) That kind of stuff sticks in the little areas and can cause problems down the raod. TIG is much better because it tends to be a better weld and no spatter.

I should have my car fixed. I just snaped another rear axel last night. I hate having a welded center diff. At least i got 2 spare rear axels at house.

I ended up with a locked centre diff (VC actually locked up), and I can concur - it sucks. Breaking the centre diff won't be cured by welding it - welding actually makes it weaker.

You need a stronger diff, or better launch technique.

yea don't do it. Get another center diff. It might be cheeper just to get a JDM tranny. With a welded center diff you will go through rear axels fast. I see you have a 91 so you probly still have you 3 bolt. I have had my 1G almost a year and i have snaped 3 rear axels. I just hope that a 4 bolt will be able to hold up to it. This is just my view if you get a welded center diff don't daily drive the car and that 3 bolt will not last very long at all. I snaped my last rear axel when i was making a U turn. That is how much extra stress it puts on them. Hope that info helps

Now I'm leaning towards a 4 spider diff.. Where could I find one at? I know TRE sells them but I don't have months to wait on them. Any info would be great. Thanks

with the spider gears if i am correct you can not dyno your car. I don't know why but i have heard that with the speed design spider gears you can't dyno it. I don't know if its the same for the TRE ones. Just some info for you.

With a 4 spider you still cannot dyno the car unless you get a vce coupler for dyno only. A welded diff IS the strongest way to go but does put more stress on the rear axles.

MR shepherd is a 4 bolt rear end strong enough to handle a welded center diff for daily driving? if not would you reckamend getting racing rear axels?
