Like the title says, are there any things that need to be done PM wise not on the maintenance schedule? At my 60K I did: PCV valve, PS fluid flush. I should have replaced the acc and ac belt (it shredded at about 65K- looked OK at 60K). Anything else? Also, on the same lines, what type of oil do y'all for the rear diff ('02 WRX). Troncalli initially gave me the LSD oil (I think for the STI). The service manual I downloaded here (and owners manual) indicates same as the transmission. Based on that I took it back and got the trans oil. Is that correct?
one thing i learned as that even if the belts look ok, change them! i have gone through 2 serpantine belts since i bought my car and it doesnt even have 90k on it, bought it with 85K. the first one was never changed and the second one was dry rotted from sitting on the shelf so long ... thanks dad.
I used Royal purple 75w90 gear oil for both front and rear diff. should be the same with your WRX just less fluid.
