These bars are becoming the subject of 3/5 threads nowadays to the point I don't event want to ask, but seeing the pictures constantly makes me wonder if anyone is looking to see if the mounts (u-bolts) on the axle are shifting at all?
Good question to ask. I wondered the same thing when we first installed the Whiteline rear bar as well as their Watts Link, then later when we installed their rear LCA relocation brackets. These U-bolts are actually a somewhat common way of mounting a swaybar by even the OEMs, back in the day.
We have had these bars on since last... June or July? The car has been on the lift for pre-race inspection a dozen times since then and this is one of the things my technicians here at Vorshlag look at. These U-bolts haven't loosened once, but we'll keep eyeing them. The car has been tracked and autocrossed a bunch of times since these parts went on.
We've had the cast aluminum, Whiteline Watts Link supplied diff cover off a couple of times, to replace/rebuild differentials. The first time the diff fluid was leaking a
tiny bit, so they took extra care when sealing the cover each subsequent time. That's the only thing we've had to do over - the diff cover seal, but it was probably our fault for not getting the surface of the diff housing perfectly clean and/or not using enough RTV when installing the cover. The WL rear swaybar has been flawless.
If you look closely there are paintmarks on all of the critical suspension bolts (normally on the nut side, most of which aren't visible in the two pictures here) and even the axle tubes (red paint). We've been worried about the axle tubes slipping relative to the center of the diff housing (they are pressed in). So far, so good. Now that this car isn't running SCCA Solo ever again, we will go ahead and weld the tubes to the housing, for extra peace of mind.
Cheers,
