I was told that the 97's have enclosed bearings or something like that and they don't need to be greased. Personally I think thats a crock o crap. What do you guys do about them???

 

The stock ones are sealed and you can not grease them.
I redid my front suspension at 135k and the new lower ball joints are greaseable but the new top ones are sealed.
They seem to do alright sealed so don,t worry too much about it.

 

You mean something GM did actually was meant to last??? They really don't want you to bring it back to the stealership??

thanks bud

 

Yes some things they actually did right, like the serpentine belt system.
