Has any one heard of the thrust bearings on the crankshaft going bad around 100'000 miles? I have friend who has a 97' and his truck sounds as if there is a lifter problem. I was wondering if I can get more insight on this. Thanks.

 

tell your friend to search for a post for what build date on the motor for the bad head gaskets first. That may solve your problem, but I havent heard about bad thrust bearings or that there are any thrust bearings? Do you mean main bearings?

 

I sure will.
