Just a heads up to anyone who is thinking of using these. I bought these from Rock Auto and installed March 2018. Both sides already worn out. Granted I probably have everything working against me for premature wear. Bilstein 5100 leveling struts set at 4th notch, larger tires, and I drive 30 miles of washboard gravel roads every day. But I thought they would last longer than that. Started to hear a grinding noise when turning about a month ago. Sounded like a rock in the dust shield. Power washed and lubed everything and it was good for a few weeks but came back. Finally decided to jack it up and sure enough the lowers were shot. Went with NAPA brand this time so we will see. I guess it will have to be a regular item to check at oil change. The originals had been in there for 160k miles and were still good but I needed to replace the lower control arms so I figured I'd get it all new while I was in there. Would have been a good idea had I used good LBJs.
