I just put my 2001 LS430 on the rack and notice my lower arm front bushing are crack on both right and left side and the car is shaking between speeds of 40~70. I have been running 20 in 3 psc wheels for on my ride for the last 5 years and I'm sure it time to replace them but "what should I use"? The OEM type or Polyurethane. HELP ME OUT!

 

Polyurethane should be fine to use. Supposedly it's better than OEM bushings. Go with whichever is cheaper.

Where did you find polyurethane bushings? I didn't think they made any for the LS.

 

yeah cuz I can't find them anywhere

Found a set on ebay for $143.00, they are from some company called ARMSTRONG.

 

They will likely be stiffer, giving the car a slightly harsher ride. If you get them let us know how they feel.

 

I think I've heard of them. That's around the same price as the OEM ones if I'm not mistaken.

 

Having a harsher ride is not a good thing, so I would like to hear from others who have done it.

 

Mine have been cracked for almost 3 years with no rear noticeable issues except for an occasional groan backing up or over speed bumps.. What would the reasonable labor amount be for replacing both bushings?

 

Usually aluminum bushings cause a harsher ride. Polyurethane ones shouldn't mess with the ride quality. On the SC forum a lot of guys use the polyurethane bushings and have pretty good experiences with them.

 

stupid idea... nuff said

 

Adus makes poly bushings for our cars. But only the lower control arm bushing I believe

 

stupid idea stemming from ignorance.. these bushing are hydro-mechanical... stick piece of hard plastic instead of it and lose the ride completely... japanese engineers are not dumb...

 

What you say does makes sense but as I said,,,,,, I wanted to hear from someone who has done it.

 

I've replaced a rear trailing arm bushing on my ES300 with a poly one from Adus, Lexus didn't make an OEM bushing by itself and the only other option I could find was to buy a whole new knuckle from Lexus which was ridiculously expensive. The rubber bushing was so bad it sounded like an old mattress squeaking in the winter. $25 and an hour later, and it was like new.

I noticed no difference in ride quality with the poly and it was easy to replace. Understand though, this was the rear of the car, not the front.

The big mistake people make is when they take an older car that needs all the bushing replaced and they replace them all with poly, that's when you get a teeth-rattling ride.

If you can find a rubber bushing, use that, even if it's more money. I'd only use poly if it's an application where you're forced to. For some strange reason, aftermarkets companies don't seem to go after making rubber, OEM-like bushings like they do poly.

You might also want to look at getting an entire new control arm assembly that has both new bushings and a ball joint.

 

it's not just rubber in this case... it's a valve-like mechanism encased in hard rubber....
people who replaced faulty one know this. when you press out old one it tends to rip and show it's innards which is... intricate.. it's some high-tech right there
