I'm going to do my ball joints soon but want to start ordering stuff for them. I'm looking at ordering everything from RockAuto but they have 2 different Moog UCAs. RK series Model #s RK80308 $42.79 and RK80306 $41.99 and CK series part #s CK80308 $62.79 and CK80306 $62.79 what's the difference between the RK and CK? Thanks!

 

Anyone?

 

The only difference I could see is one is driver's side and the other passenger.

 

I just went through this. I believe the cheaper models are like the stock ones, not greasable. The premium have the 'gusher bearing' that is greasable.

 

Ok great thanks! I'll go with the grease able ones!

 

On the description on the moogs it show both to have the gusher bearing....

 

moog's r series is a budget series... I can't be sure, but i'd guess the description info on their site about the premium c series is the difference
