My contribution is this: I bought my car from a lady whose husband (a member here) slipped into eternity about 18 month earlier. She had no record of service and the car was 8 years old with 28,000 miles on it.

I set out to bleed brakes, clutch, change differential fluid and trans fluid. The car got a new battery right away. The cooling system got a flush. I never did change steering fluid, but I should.
As I said above, what I SHOULD Have done is replace the steering stabilizer before I did anything else.....
