Has anyone installed a RLCA bearing and subsequently removed it? If so, why?

This is very interesting. What sort of NVH do they complain of? I have the RLCA and diff bushing lockout. My issue isn't with noise, it's more a bouncy/unsettled ride at speed. Around town it isn't really that noticeable but at highway speeds especially 75-80 and above it feels unsettled on anything but a completely flat surface.I did when testing on my 2016 GTPP.
The only thing I liked better without them installed was the transfer of NVH was less with the stock bushings - however, I had a fully modded IRS system.
IMO, the absolute BEST combo of parts for the average person for their streetcar is the CB005 (or comparable) and the RLCA Bearing.
This is what I have my GT350 Customers start out with, and practically refuse to sell them parts above and beyond that until they get some use on the parts and provide feedback.
What I find very common is customers typically complaining about NVH when they have diff bushing mods installed, but almost always when both the diff bushing AND the RLCA bearings.
Sounds like too much damping in the lower rate portion of the spring. Is it bouncy as in unsettled by undulations and changing surfaces at highway speeds, or is it more of a rhythmic oscillation?This is very interesting. What sort of NVH do they complain of?

I don't recall feeling it like this before the RLCA and diff lockout installed but unfortunately they were both installed at the same time. So I can't attribute it to one or the other.
My original theory was/is that my progressive springs are contributing to it as well.
Did you tighten everything up from the install at RIDE HEIGHT? Your whole rear suspension assembly could be bound up if you tightened all the bolts while it was sagging.This is very interesting.

Undulations and surface changes.Sounds like too much damping in the lower rate portion of the spring. Is it bouncy as in unsettled by undulations and changing surfaces at highway speeds, or is it more of a rhythmic oscillation?
Definitely agree for anything considered bouncy. This sounds more like a damper issue.Sounds like too much damping in the lower rate portion of the spring. Is it bouncy as in unsettled by undulations and changing surfaces at highway speeds, or is it more of a rhythmic oscillation?
Agree to an extent, being that the RCLA bearing is not affected by bind as much as the stock buching but there are still other bushings in the rear that need to be torqued when at ride height.Did you tighten everything up from the install at RIDE HEIGHT?

This is another good recommendation. Couple these from Steeda with a quality set of rear dampers and bounciness should be reduced or eliminated.Do you have the billet upper shock mounts installed?
Yeah. Sounds overdamped in the lower rate portion of the spring. Your planned changes should help.Undulations and surface changes.
I used an ancient Harbor Freight press using an assortment of homemade adapters to get it to work. The control arm is heavy and awkward to get a straight shot at the bushing/bearing. 1st arm gave us a fit, but the 2nd was easy as pie. Not a project for the squeamish. :headbonk:What method is everyone using to replace these? is it recommended to get the BMR BRT001 tool?
Gosh, I am sooo excited about doing this. /sI used an ancient Harbor Freight press using an assortment of homemade adapters to get it to work.

If I had to do it over again, I would heavily consider doing the BMR shop swap where they send control arms with the new bearings already pressed in and you return your stock control arms. The amount they charge for the service is peanuts compared to the aggravation.Gosh, I am sooo excited about doing this. /s
