One of my brothers cars had a rattle due to crappy rubber bushing in upper mount.

Many threads I have read (on toyota avalon my other car) people have had problems with upper mount nuts loosening causing rattles and they had to retighten them.

What about the quality of the rubber they used does it look good?

It looks very good. Pliable and heavy duty. Here are a couple pic's of the top and bottom isolators on the rears...

A follow up to the Arnott coilover installation...

I installed the front Arnott coilovers this weekend on my 91LS. They ride great! I'd say they are identical to the OEM. I didn't get to the rears, probably next weekend. I had one small problem. The three threaded bolts that go up through the fenders to bolt the top of the coilovers in were off by about 1/16 of an inch. It took a little persuasion to get all three studs through the fender well holes. Other than that, I highly recommend them at this point.

Is there a reason you decided to go with the Arnott's instead of factory OEM struts?

100% new including springs for $600... Thought it was worth a shot. Very happy so far with the results.

I will be purchasing a set in a month..Thank you VERY much for the continued feedback Jim. =)

I recently installed a set of KYB GR2's on all four corners. The local installer I used botched the lower bushings by not re-installing the springs correctly. Long story short, they are going to pay for replacement struts, and not being happy with the KYB ride, I am thinking of paying the difference and getting the Arnott's. Thanks for your feedback, I just want my Lexus ride back.

KYBs do need to season a little. Usually takes about 5-10,000 miles. They sound exactly like what I want. Stiff shocks with a couple of hundred pounds of tool box in the trunk will give the precise control I want over RXR crossings and active country roads. I do not like having a car full of passengers landing on the bump stops.

Just heard from Arnott that the 10% discount coupon code 74V4-W7D has been extended through the end of 2010 for Club Lexus members...

Just had Arnott coil overs installed. Went for a short ride around town looking for bumps and potholes. I have a small rattle felt through the steering wheel when encountering sharp bumps. It was present before the change to the Arnott's. Have already changed strut rod cushions. Any ideas? Will take a two hour road trip this weekend to get a feel of how she performs on the highway. So far the car seems to handle much more like the factory ride. So long log truck, I mean KYB's.

Sway bar links/bushings? My mechanic friend mentioned those as a likely culprit when I asked him about my front end clunking/rattling. I think it's mostly the strut rod bushings for me, but since it wasn't for you, I'd try replacing those links and/or bushings.

Great. What did they charge you to install them?

$250 for all four corners.

gah! they were already assembled! It would have taken me two hours to do it with lame hand tools!
