Notes:
Non-Knurled ball joints recommended for replacing non-knurled ball jointsDue to these ball joints being tight tolerance, metal on metal ball joints, proper fitment is critical. Using the wrong style of ball joints can cause significant steering issues. We always recommend installing non-knurled ball joints until non-knurled ball joints are no longer a press fit into the axle end forging bores. If your axle end forging bores have been enlarged to the point that non-knurled ball joints are no longer a press fit, knurled ball joints are required.
Use of the improper ball joint style for the axle housing voids our lifetime warranty. It is up to the installer to verify the proper ball joint style is being used.
Compatible with RCV axle shafts

Good product
Scent: Assorted
Good soap set I like the smell and the 4 pack last a good while. My only complaint about the soap is at the end it was soggy soap and hard to get it to dry.
I will give the other bar a try if it does the same thing I might not be using this.
