So after tracking my car a number times my rear diff has started complaining. Each time after a thrashing it makes some clunky noises at full lock. Luckily I have a spare.

Now I'm wondering if I should have a go at welding my old one and using it at motorkhanas. Will this cause any problems on an AWD? Given it is a throw away now I'm not afraid of damaging the diff itself, but what about the rest of transmission? Will it put too much strain on the gearbox or centre diff?

Is this a stupid idea, or worth an experiment?

Go a good plated and just leave it in there all the time

Happy days and much more friendly (on track) and predictable to drive

I agree with Matt. How annoying would it be to swap diffs before every event.

And you'd need a spare pile of shafts too because they'd get munched.

If you could find a suitable ratio R180 youd be set

I absolutely abuse mine and it loves life :)

I'd love an r180 for air locker goodness ;)

But not for track work...

And even with an r180 you'll still chew driveshafts. How quickly you'd do this in either application is anyone's guess though...

Proper r180 shafts are pretty damn tough imo

Hes not drifting or anything so should handle it fairly well...mine have handled lots of hillclimbs and 100s upon hundreds of clutch dumps from launches with proper semi slicks...yes i still carry spares..but no need for them as of yet

My old gen3 sti r180 shafts are still going fine after many years of work behind a punchy 240kw engine

Hmm. Might just throw my spare in and leave the old one alone then.

Changed the oil and the problem disappeared even after absolutely flogging it around Oakburn yesterday...

 

A mechanic gave me some diff additive also, is this safe to put into the old R160?
