hi has any body ever put a gear box additive or any thing else in there gear box to reduce noise? mine has got a whirr and the faster you go the louder it gets, think it could be the front diff worn, it not a wheel bearing! any body with any advice would be grreatful

 

speak to paul at zen performance, hes the one of the best subaru tuners out there with decent prices, ive got a similar problem and have been told i need a rebuild due to the mileage and abuse the car gets, he quoted me £650 for a rebuild on a 93 wrx which is very reasonable compared to the others, most people on here would say to keep away from additives as they dont really work

 

I put some Molislip with my gearbox oil as it was making an awful noise on over-run. Hey presto, noise gone. I understand that this is not a permanant fix but for now its Hot ****.

 

how much did you put in mate and where did you get it from? the noise is driven me mad so any thing for a little piece for a few miles

 

One tube, £7-8 from Halfrauds.

 

ok il give it a try thanks mate any things worth a try

 

STOP. Depending on your model/gearbox you have a centre viscuous diff and the possibility of a front diff.
Gearbox lubrcants can render the diffs U/S.

 

Erm maybe, VC are sealed and the oil doesn't affect them its only plate diffs that are affected by the oil, so unless the OP has an STi R/RA he is OK, but if he does, then yes he needs to be careful (the imprtance of filling in my scooby!)
