frame to diff moun bracket broken. options?
 

well I just got my "broken" differential mount out, and found the mount to be intact, but the mount came out with the top end of the 90 degree bracket that holds the mount to the subframe.

wat are my options now? It broke accross the holes, so I could tighten it down and pinch what is left of the holes, but I imagine it would just slip out.

what do you guys think



edit: the bracket is like a W. both sides are fine, its just the part that comes up in the middle thats broken

damn, you need duct tape.

i found a used subframe on ebay from a company called 915racing great company all they have are rx7parts got the subframe shipped for i think like 70 bucks all together

This is something I had to do on a customers car. I had to think what I could do without dropping the subframe and welding a new bracket for the diff mount.
It works.
You need a pinion snubber. Search for it. You should be able to get it at any auto parts store like this one I used:

You should still mount the diff mount but use the snubber to push it down in place since without the bracket to hold the diff mount, it'll slap up and down everytime you get on and off throttle. It's easy to install. Remove the rear bins, pull out the carpeting and drill the appropriate size for the shaft for the snubber. I installed 2. One for above the diff mount and another right at the edge of the rear end. This keeps it solid and try to "twist" when getting on and off throttle.

You need to drop the rear subframe by unbolting the 2 ends and the end link. This will drop enough for you to install the snubber. I'd drop it as much as you can and iinstall the snubber so there isn't much gap between the mount and snubber. When you install the rear frame, it will compress it together. Use a floor jack to bring up and down.
Hope this helps.

+1 for pinion snubbers.
have a new diff. mount welded on, could probably be beefed up too.

I've got an entire subframe sitting in my garage. If you need a new one, let me know. It's really not hard to drop a subframe and do it right the first time.
