...This reminds me of the 80 Cutlass I bought for $25. right out of high school...Couldn't open the driver door,brakes were bad- but, Ah, yeah....memories....
#1 Keep oil in it...someone elses used oil is better than none.
#2 Popping/jolting... Are all of your tires the same size? Are fronts more bald than backs? vice/versa?
You would be suprised how this will affect an AWD... even if they are the same size/make. Move one front tire to the back-
Have one bald tire, and one w/tread, on the front...
and one bald, and one w/tread on the back...
This kept my (non Soob) AWD on the road another 6 months.
I couldn't believe it, but it's true...
Keep the front ratio same as the back. No matter how "wrong" they may be... Good luck! -K
