I purchased the RCF LCA bushings off Impex Japan for about $138 CAD.

I did the replacement myself. It took me 2-1/2 hrs as one bolt was rusty and hard to remove or tighten. You’ll need 22mm, 17mm, 14mm sockets, jack, jack stands, paving stones, blue Locktite, breaker bar, and torque wrench.

I drove it the car around the block and it feels good. I didn’t notice any difference in NVH. I’ll have to drive it longer and report back.

Any comments on the front bushings of the LCAs?
Also, my rear drivers side sits 1/4 inch lower. Problem?

 

Pics of old cracked bushings. Cracks can be seen on both sides of each bushing as well.

 

Now that I've driven the car for two days I can report back my findings:

1) The steering is more precise and a bit lighter in that it's easier to move the steering wheel when parking.

2) The ride is more smoother and there is less road noise.

3) Because the ride is smoother, the acceleration is better because of less resistance. The tires might not have been planted firmly on the ground before the bushing change?

4) Although I still feel road imperfections, the vertical oscillations appear to have diminished by at least 25% to 50% (depending on how bad the road is) making the ride more comfortable.

For sure this is the best $138 that I've spent despite having my whole body ache for two days doing the install. It was hard loosening and tightening the bolts because I couldn't use my legs or body weight to my advantage since I was lying down on the ground.

 

Can you post pictures of the difference in height? Are you certain the subframe is tight on that side? The long 22mm bolt.

 

Yes, the long 22mm bolt is tight as I torqued everything with a torque wrench.

The difference in height was at the back and not the front.

Anyway seems like things have changed when I just measured from the car sitting in the garage. I guess there are bound to be differences due to unlevel ground.

 

Ah ok I misunderstood. I thought the height difference was. When you bolted the bushing, and maybe measured height clearance on them.

 

That height difference is normal, not sure why though. Mine also sit higher on passenger rear corner about 1/4 to half inch. I guess over the years front driver corner get “settled” more since most time we drive our car without passengers.

 

I'm looking to do this, and what you've said here is music to my ears!
