GL X166 Active Curve Sway Bar bushing replacement?
I have a 2014 GL550 with Active Curve System (Option Code 468). My truck has been squeaking going over bumps recently. Dealer diagnosed it as bad bushing on the active curve sway bar (also referred to as stabilizer bar, anti-roll bar, and/or torsion bar). The dealer cost is $3300 parts plus $1200 labor. Online dealers have the parts for $1,8XX and this is a job that seems relatively straight forward so I will do it myself, but it seems unnecessary to replace the entire bar if just the bushings are bad. However, the dealer said is that the mount is not removable from the bar so you cannot just replace the bushings. I am wondering if anybody has experience trying to replace the bushings only or if I have to spend the $1,800 for a new replacement sway bar? Any input is appreciated.

“Normal” MB practice is that the bushings are glued to the bar and not sold separately. Aftermarket non-OEM loose bushings may be available.

I found the squeeking sound came from the pasenger strut. After I removed the lower control arm, I held the bottom of the strut and shook it. The same squeeking sound as it went over the bump.
I ordered both struts to rrplace and the work is coming up this week.
I also checked the upper control arm, driver side is bad too. New parts also coming.
There is no point to replace just the bushings because the work you removed the entire part. I would rather spend a little more to have it pressed correctly.
Just some update.

No other solution, unfortunately. I bought a used one on eBay for around $700 and then a quart of the special synthetic oil for the system. It was a relatively easy repair. Hardest part was getting the under shield bc I have the off road package and a bunch of the bolts were rusted. Otherwise it was just remove the bolts at the end links, remove the bolts on the mount, and then there’s one bolt on each hydraulic line.
