Front Caster/Torsion/Lower Control Arm #2 info
OK, so I have a 93 GS300 here. Both front caster rods (OEM lower control arm #2) have bad bushings. I found a pair of clean ones at a local JDM shop. I took the old ones with me to match them up and they looked identical.
I destroyed the old cam bolts as I had to cut them (seized in the bushing) so $50 later, I had 2 new bolts.... that didn't fit the sleeve in the bushing. WTF!??
As it turns out, the 2nd Gen GS300's use a different design bushing in the identical arm after 97. The bolt is the same from 93-97, so the bushing size would be the same even though the arm part number changed, possibly due to supplier change. The sleeve inside the 98 up bushing is stepped, and the corresponding bolt also is, plus there is no cam on it.
FYI - the bushing ID on the pre 98 arm is uniform at approx .630" whereas the later arms, although identical in appearance otherwise, use a stepped bushing ID of .750" at the top and .560" at the bottom. The pre '98 bolts won't fit post '98 bushings and they barely fit through the upper hole on the subframe, but even then, there is no cam to actually adjust the caster.
Pretty frustrating. Anyone else run into this problem?

Still trying to find the right answers to this. I've been scouring the net looking for an aftermarket option to the pricey Lexus #2 front lower control arm (48670-30140 LH or 48660-30140 RH) by replacing only the bushing itself.
So far, all bushing suppliers that indicate they have '93 compatible bushings are wrong, as per my first post. I have contacted one last supplier, TopSpeedAuto in TX, (part# TRLXGS300-FLAB) and I'm waiting to hear back. They also show the upper arm bushing kit (TRLXGS300-FUAB).
If anyone has already had experience with their bushings and can verify that they are compatible with the G1 GS300, LMK. We would all like to know as I'm sure I'm not the only one replacing bushings on a G1.

I know this post is old but what the hell. I recently found out from doing a brake check that the lower control arm 2 bushings were bad. They sell the lower control arm bushings for arm 1 and 2 on ebay for 50 bucks for one side. There is no need to replace the whole arm, unless it is damaged.
