- Looking at the pictures of these LCA from sankei 555. I do not see gap, between C clip of LBJ and control arms. A plus IMHO.
Kurt @cruiseroutfit can you confirm "no gap"?
- Nice to have alternative. Cost for one. Alo: Toyota' upper and lowers, could become NA anytime.

- Be interesting to see how they stand up over time, compared to OEM.

I've installed a lot of 555 LBJ and a lessor extent upper 555 (UBJ) ball joints.
I've also had to replace some 555 LBJ. None that I have installed But ones that some very well know shops in my area, installed. In each case I found the boot a hole In each case history indicate low miles on them. I suspect the boot in these failed ones was not removing during install. Which can resulted in a damaged boot. Additionally, 55 has a glob of grease in boot. This grease needs packing in and around ball and its steam, to be of any benefit. So failures I've seen, may be from improper install.
But I've had one other concern with 555 ball joint also. They pressed into OEM LCA to far. In that they press in about 2 to 3mm deeper, than OEM. This results in a reduced gap between steering knuckle and LCA. Which compresses boot more than needed. Sometimes I see these boot fold inward. This condition is further aggravate in a lifted rig. This reduced gap, has had me concerned that it could pinch a hole in boot on full droop or even normal driving. The locking C clip, when Ball joint fully seated, has the same amount of gap (of 2 to 3mm) between it and top of LCA. I've often wanted a spacer to place under control arm in seat (between top of ball joint seat and lower (underside) of seat of LCA) where ball joint housing is press up into. Which would increase space for boot.
