3.73 whine

[98mstanggt]

Did you make sure the ring gear bolts were torqued properly and Lock-Tite was used? I just had to have my rear-end rebuilt because we forgot to do that when we put in my 3.73s. Over the course of about 8k miles, they backed out and shot through my diffy cover!

Man i really dont know ha ha ima try to break the rear in this week or next week either way gotta find out what the problem is...........


josh0092002 u had any luck yet finding out what the problem is

no man i havnt, i still dont know, ive been reading up on it, but i just have not had the chance to get out there an crack open the rear end. iam guessing however that it has the stock shims back in it. but other than that again i dont really know :hammer:

Watch him check the backlash and make sure that its within spec.

When installing ring and pinion any problems are due to the installation mostly.
The only gear brands I ever seen whine or make noise was Motive or Richmond.
Stick with FRPP ring and pinion in your Ford you will thank yourself in the long run.
