Lower Control Arm (LCA) Bushings Part Compatibility (GS and IS)
Hello, I recently read a review and noticed that part numbers (48075-30030 & 48076-30030) from the GS and IS could technical adapt as long as the washer is removed.
Does anyone have any experience with using these part numbers for the 01-06 LS430?
I've noticed some aftermarket LCA bushings on eBay and would prefer OEM if they are compatible. I don't want to go the route of pressing in a new bushing.
"A nice alternative is to use the bushing assembly in the GS & IS part #s 48075-30030 & 48076-30030 [bracket with bushing] and it cost about $70 each - can be installed by removing the LCA washer to fit. This avoids the cost associated with pressing out & pressing in the old & new bushing, respectively."

Threw them onto my car since I didn't want to bother having to press them in to the original brackets. Got the ones with +20' caster. They ride a tad bit rougher but more notably, transfers more road vibrations into the steering wheel. Added caster tightens up steering a tad.

I installed the OE RC-F/GS-F bushings today on my 02 LS. Install was easy and totally worth replacing my very worn and cracked OE bushings. Results = good. I can't compare them to the IS bushings, they look the same in pics. I used the part numbers Peacebay posted. Feedback may be slightly harsher, nothing I'm concerned about at all. These seemed to solve a low speed clunk over dips/cracks I was having. The front end on this car feels pretty tight and I wasn't sure what was going to fix that super annoying low clunk. These seem to have taken care of it. Steering seems slightly tighter. On the highway I have noticed zero difference so far.
Hope this helps someone.

Thank you for the recommendations for the RC-F/GS-F bushings. I'm going to give those a trying and report back my experience.
Anyone have thoughts or experience for the the aftermarket options specifically the Moog upper control arms and lower ball joints?
I've read mixed reviews and cost is much lower than OEM. I prefer to go OEM, since I've always used OEM on anything I replace including the oil filter and didn't know if anyone has had experience with Moog.

Proforged is the best option by far for the ball joints, upper arms should be OE or B&A imo since the moogs do not have as good of bushings and quality for non-US cars is spotty as of late. Not sure why but it's a thing

Fully agreed on this one. That’s the setup I have.

Here is my learning from experience: as long as you stay away from poly and incorrect installation, the rubber is there to isolate, not harden. However, when it comes to steering, I suggest replacing steering rack bushings as there might be lots of play there if you feel imperfections of the road.

Interesting point m, but why is my LS 430 front end is smooth on teins and IS bushings?

The 02 handles better and has feel, the 06 is a cloud that glides over everything. Both are worked as designed

I was able to get two for 40 a piece. They seem like old new stock.
