How often should the rear axle lubricant and limited slip additive changed? My chiltons manual recommends every 7,500 miles. That seems excessive to me.

 

15k comes to mind for some reason.

 

Isn't that almost twice a edit: YEAR for a daily driver? Dayum!
I would think that changing the fluid more often would be the reason of having a manual tranny and that your beating the living crap out of it...especially after throwing gears like 4.10's or something.

 

I also believe it is 15K.


Twice a month at 7500!?!? Yeah, if you drive your car 180,000 miles a year!!

 

wtf, woops..what the heck was I saying when I posted that. I meant a year. I must of been sleepy or somethin...

 

I do mine every 30k. Once a year when I used to beat on it all the time at the track.

 

I do mine once a year when I do my normal yearly mantinance stuff like fule filter, tranny service, fuel injector cleaning, coolant flush and other odds and ends.
