it's cheap and would be great if it worked properly, i got mine and tried to screw the bottom and it didn't work, something is wrong with the threads on the bottom or the rod is bad after barely twisting it with pliers I tried to stuff the bearing and there is a hole at the end of the center rod meaning all the grease I pumped went through the Bottom came out, nothing goes to the bearing itself. What is the hole at the bottom of the B-pillar for? I returned it and received my refund. I'd probably take the comfortable $20 one.
