I have a 1969 Oldsmobile 442. Replacing my leaking steer shaft seal in my gear box tomorrow. Ive used power steering fluid since 'Ive had the car the past 5 years. What is recommended? or what is bette?,Atf or power steering fluid? Like I said I've been using power steering fluid for this long, should I stick with it?

 

When I replaced the steering boxes in my 63 Riv and 71 Cutlass, I flushed and refilled with power steering fluid. Been 10 years with the Riv and 1 with the Cutlass with no problems.

 

I used power steering fluid in my 65 when I flushed it, works great!

 

Thanks for all your input. I attempted to replace my steer shaft seal in the gear box. Old one came out great. New one pressed in wonderful. Guess what????? The junk still leaks just as bad if not worse. I'm feed up with it. Blowin $100.00 bucks this week on a remanufactured one so I can just be done with it.

 

same thing happened to me. the shaft looked good and all but it leaked worse. i just figured i must have cut the seal putting it in. i said heck with it and got another box also.
