Thanks for the heads up! I'm planning to install it as centered as I can get it, but good to know that it could potentially be adjusted for certain conditions.

FYI the Moog joint is indeed too wide for the bracket, so I also had to get creative with widening it a bit:

There's one benefit to this though. Say you're slammed, you could install the MOOG bearing further outwards. It would correct some toe in like the Garagistic units. Or maybe you're lifted, you install it further in. For stock application try and center it.
I was just about to post about this.
It looks more and more like this is the best rtab solution. The ability to dial toe is the cherry

A quick look at their bulletin PDF gives various part numbers with their application. The closest fit is a Camry part number K200786 ($20 USD on RockAuto). MOOG does not provide dimensions but we know it's for a 92-01 Camry, and ACDelco 45G9207 is the rubber bushing for that application. It's dimensions are:

bolt hole: 14mm
bolt sleeve length: 50.04mm
bushing OD: 59.944mm

Looks like a match except the bolt hole is 14mm, and the OD is on the looser side. My experience with the MOOG vertical bushing is that it's on the tighter side of fitment. The stock bushing I can remove with threaded rod, nuts, and receiving cups, but the MOOG part required a shop press to install. Fair to assume its on the tighter side of tolerances. We would need to drill the trailing arm bracket for a 14mm hole and an M14x70 grade 10.9 bolt and nut.
I did this swap today and found some different specs...

Moog OD = 3.376”
M3 trailing arm ID = 3.360”

16 thousandths sounded like too much for interference fit so I turned down the Moog parts for a nice press fit. While I had the lathe plugged in I made a pair of 12-14mm bushings to enable retaining the stock 12mm bolt.

Interesting.. I'll have to pull out my bushings and check dimensions. I'm not against doing a bit of machine work. Did the width of the center "sleeve?" require you to expand the RTAB bracket? I'm considering turning down that area to avoid any modification to the bracket.


My trailing arms are currently being sand blasted and powder coated...
Then I can finally install these damn bushings which have been sitting in a box for a year.

The OD/ID difference makes sense - I had to chuck the bearings up in a power drill smooth them down with some sandpaper (especially the leading edge) to get them to press in. They came out pretty easy though.

Moog part wouldn’t slip into bracket.
I didn’t measure how much the bracket needed to spread, it’s not much. It expanded easily by inserting OE bushing and a screwdriver (universal wedge/prybar) then applying some hammer.

If you’re powder coating suspension parts it would make sense to turn down sleeve...
