MY05 JDM Sti rear diff backlash question **youtube**
Hi guys, after spending some time on the internet and reading through pile of post about knocking in the rear diff I decided to ask you about the backlas, I've been told by a Subaru specialist where I took a car for check up that it's normal and there is nothing to worry about, what's your thoughts?? There is about 5-6mm play on the rear diff, here's the link to the youtube where you can see what I'm talking about. Thanks |
Just forgot to add that the clunk can be heard when on and off the gas especialy in the low gear ie crawling in the traffic
|
If you have the wrong gear oil in the diff the clunk can be louder ie 75/90 and changed to the right 90ls oil be it fuchs or mutual what its says in Jdm owners manual for rear diff and the clunk is very quiet now .
|
I did changed all oils when I bought the car and I used Motul gear 300 75w/90 for diffs and gearbox, is that wrong grade ?What oil should be used then?
|
you want a specific LSD oil in the rear of that car.........
we carry various options in stock depending on exact use, wether road, track, competition, etc........ |
It's a road use car, unfortunately I can't read japanese so owner manual didn't gave me info on what oil to use but I read here that 75w/90 will be ok to use on cars with dccd unles there's difference ilbetween jdm and uk dccd cars?
So what grade should I use for jdm dccd to reduce the clunk? Thanks |
I have backlash in my spec c, just got used to it
|
It seems that I'll have to do the same ;) what oil do you use in the diff?

Thanks Its 90 ls oil what I said in my above reply to your post and says in the maintenance note/service book lsd 90 and I mentioned fuch or mutual do a 90 ls oil .I did the 75/90 in the rear diff and the clunk was louder .Put in the right oil 90 ls and diff is quiet now .This is in a 05 Jdm Sti impreza that I have |
Thanks Dipsy, I was trying to get 90 ls yesterday but with no luck so I just ordered one online, as soon as it arrive I'll change it and give an update, hopefuly the clunk will be recuded ;).
Thanks |
Oil changed today for Fuchs racing gear 90ls and ther's still clunk, it's not that loud/metlic though
