I did notice that the fittings on mine would take grease but it had no where to go once it got in the tube, so I pre greased the tube and bushing some before assembly, I can see where that could be an issue latter, the SATV ball joints will not take grease also, I had to pre grease the joint with a needle tip down the side of the boot seal, I will have to keep an eye on that and when them bushings do wear out I will try the RB3 bushings, I did get Your wheel spacers and door bushings they are Very Nice Work Great,, Thank You Very Much,,,,,
