new suspension making noises

2dooreighty5 · #1 08-05-2012, 02:49 PM

ok guys so i recently did all new suspension on my caprice...new springs all around...new shocks all around....all new ball joints and all the tie rods brnd new too and new sway bar... after installing everything i took the car to the shop and they did alignment and said they checked everything out and said i was good to go. The reason i did all new suspension in the first place was because a noise i was getting which i believed to be a bad ball joint so i just went ahead and did everything since i had to pull the control arms and what not. after everything is said and done the car is still making the same noise....its like a clicking noise which only happens when i apply the brake and the car lurches forward it sounds like a poppin like something isnt tight and the car is moving forward on the frame or something....it doesnt happen in reverse and happens at all speeds sometimes one click sometimes 3 consecutive...ive lost my mind tryna figure this out...any ideas guys really would help

pretty sure its only on the left side.

also its not like a quite popping or clicking its pretty loud and noticeable.

Did you have the upper arms off? If not, be sure that the nuts on the studs where the alignment shims are located are tight. The alignment shop should have caught this if it were a problem, wont hurt to check though. Also be sure the calipers are tight.

ya im gonna check the brakes today to see if it could be related to calipers or something loose in there...

also i forgot to mention i have cragar spoke wheels which my dad think could be the cause of it maybe...im gonna switch the too front wheels and see if it changes anything...

the upper arm nuts are tight but good idea

could be calipers or the pads not properly riding in the caliper. also the control arm bushings could be worn. the other common noise in this area is the coil springs top insulator and the engine motor mounts esp. the driver side is n/g.

i did all new bushings on both upper and lower so it cant be that

I left the coil spring insulator in there so i doubt its that

and seems if it was the motor mount i would get a louder noise

im goonna check the brakes today and see

With a new tight front end, your are probably hearing other noises.
How about new rubber exhaust + muffler hangers.

2dooreighty5 · #8 08-06-2012, 03:31 PM

the noise was their before i did the suspension

thats why i re did everything...i thought it was a bad ball joint

the exhaust is all new too cant be that....

the motor mount noise will vary. depends on how bad it is.also the motor mount frame bolt holes do get worn causing movement.

you know how to check these ? takes 2 min .

in post #2 you said it was LOUD . my experience is this slowly gets more as the breakage of the rubber increases unless you smashed up the vehicle hitting something.

Check the condition of the body mounts. A deteriorated one will allow the body to flex a bit, leading to these clunks.

THANKS AGAIN FOR QUICK RESPONSES GUYS ITS AWSOME

i checked it out today and it seams to me that when i did the brake pads i didnt hammer down the "ears" of the pads...so when they were installed there was wiggle room...

after trying to hammer them out on one side i got them a little tighter but not all the way it seemed to reduce the sound...but not completely...

im thinking the pads are loose inside calipers and its making a sound similar to a bad ball joint.... gonnna try to check out more tomorrow

thanks

with the pads install you do not hammer anything. using a pliers you bend the outer pad tabs slightly then press into the caliper . this is repeated until the pad sets firmly into the caliper. the inner pad has a clip that holds it to the piston. if that is missing you will require a new one.

also the pin rubber may need replacement if the calper is too loose.

pad/caliper noise is a rattle sound when going over bumps.

ball joint noise is a clunk/pop sound. this sound would also be heard with the other front end steering components and the motor mounts.

my haynes manual calls for you to pry up on the pad and hit the ears down with a hammer....

i guess the sound isnt really loud but its not just my metal to metal coil spring...

what is the rubber pin your talkin about?

the innner pin is good and the inner pad isnt ratteling...

i doubt its motor mounts....i had a cadillac with a bad motor mount
this noise can happen when coasting at like 5 - 10 mph and then lightly applying brakes

I will add another reason why I do not like these haynes manuals.

the calipers are held by 2 pins. they slide on these pins . the body has round rubber these go thru. if they are worn or missing the caliper will move too easy/much.

the inner piston pad is held by a clip. if this is broken / missing this will make noises.

2dooreighty5 · #15 08-07-2012, 03:21 PM

those two bolts are there but i dont think they slide threw any rubber...
they are fully tightened but the pads still wiggle in place...(not the inside)
the outside pad moves back and fourth about half an inch maybe less...\
but im almost posative this is the noise...

should i try prying the ears for the pads instead of hammering?
