Rear diff mounts

verb.zero · 02-11-2013, 11:07 AM

Okay so recenlty I traded my n/a for a TII that had idle issues which I solved. While driving the car I noticed the front rear diff mount is blown, im not trying to be cheap but I dont want spend $100 for a new one... I have heard of people welding the diff mount, what is the pros and cons of doing this?

Are you talking about welding the two "halves" of the front diff mount together to essentially make a solid mount or welding the mount to the diff itself? I don't see why the former would be a problem as long as you're confident in the weld. Personally, I don't like having solid diff mounts though as a little movement takes stress out of the drivetrain.

You can probably find a used diff mount that's still usable for pretty cheap. That'll most likely be easier than welding it and give a better ride.

Your should get rid of that complicated rear end setup and just install a solid axle...

I did notice some burnout marks at the top of road, so maybe you got this fixed already?
