One of the lower CAs are making a deep squeaking sound, is there any kind of spray i can use on the polyurethane bushings? I was told lithium grease at autozone, but it comes in a 3 dollar tub and takes to much time and mess to rub around the outside of the brushings(if you dont take them off) hoping it will go into the contact area.

What kind of spray could I use?

They have white lithium grease in an aerosol can but I'm not sure just spraying the outside of them will help. Your LCA's don't have grease fittings?

Not sure about the grease fittings. i just need something to lube them up alittle

i doubt its your bushings making the noise, but take a needle put grease in it and then do it from there and you can get it in fine places. usually the bushings dont make noise unless they're VERY bad off, and even so its faint, ball joints are usually the things that make it squeak. id look into that before you change something you dont need to.

Poly bushings are known to squeak if they don't have grease fittings.

polys are a faint squeak, ive NEVER heard a PU bushing squeak that loud, im just telling him to check his balljoints, i work on my friends mustangs from time to time and ive had 3 mustangs of my own and i just recently did work on my crown vic, it was squeaking, and i know the control arm bushings are bad but im not worried about them atm, and i had people try to tell me that it was my bushings im like ive had this situation 50 times, and 49 of the times it was the balljoints. and i told the people dont tell me your input when you havn't turned a wrench yourself. lol. but yea im just letting him know to check the balljoint.

When I bought my car it had the squeaks in the rear you are talking about. I bought some liquid wrench dry lubricant it has a silver cap. I sprayed the upper and lower control arms at all mounting points. The noise went away and the stockers will last until I can get an aftermarket control arm kit at some point. May not be what fixes yours but it worked for me.

if they don't have grease fittings why not just drill a small hole ad the grease fittings 2 them? couldn't take more than 15 minutes.

if you drill a hole thats only very temp fix, wont last long.
