rear is squeaking at all times

[95-4.6l]

Hi All,

Rear suspension is squeaking and creeking like crazy at this point. Was creaky in corners but now it's creaking just rolling down the road. Then when I get out it creaks and if i push down on the rear quarters on either side of the car it creaks.

I see rubber rings around the upper and lower control arm bolts which look cracked.. i was told everything is safe - just noisy.. (Is this correct? Is this safe?) (Shop wanted to replace control arms for about 2300.00 - or 500.00 labor if i could find the bushings separate..)

I also see a suspension support forward arm bushing in the manual but haven't found it on the car yet..

I saw another post about using silicone spray on rubber parts/bushings on the car being ok but here's some other related questions:

- If you spray lube on the rubber collars around the control arm connection points or any other rubber spacer on a bolt - is there a danger of the lube causing the bolts to loosen and undo themselves? (product i was looking at is called "Liquid Wrench" - made me wonder..)

- Does it seem like these spacers are the source of squeaking in your experience?

Thanks.

It is OK to use silicone spray or silicone grease on rubber parts but never use a petroleum based lune on rubber as it will attack the rubber.

is there ever the danger that lube sprays will penetrate into bolt threads and cause them to eventually vibrate loose?

I doubt you would have a problem.
