Knocking sound in rear end

[86-lxi]

Ok this just started happening and its pissing my off....when i'm coming to a stop I can hear and feel an intermittent knock coming from the passenger side rear and don't know what it is.

I figure it has something to do with the drum or pads, any other ideas?

try this on the rear side you think its on:

it works on the frnt and rear wheels.

Standard front end check:

1: jack up one side of the car until one tire is off the ground. The other side tire must be on the ground. I use the jacking point under the doors.

2: grab the tire in the air at the 3 and 9 o clock postion and shake/rock back and forth. slow at first. You might need someone to help look underneath. This checks tie-rods,steering rack etc. start kinda slow and work your way up a little harder. Your looking for loosness at the joints. Use common sense of course the steering wheel will move or the other tire may move if you shake the shit outta it.

3: Grab the tire 12 and 6 o clock. Rock back and fourth.This checks the wheel bearing and ball joints(upper and lower) and upper links(bushings). There should be no play in the wheel bearings.

4: this check might show ball joints/upper link a little better. Use a pry bar under the tire at the 6 o clock pos. pry up look for slop ,looseness while prying. The upper link ball joint and bushings near the body are what your looking at.


This is your basic "front end check" any good mechanic should know. It works for all makes and models of cars.

I have a annoying sound as well.

But Mines my exhaust system hitting the wishbone.

Mine started doing this a week or two ago. At first I thought it was the front brakes but now I think that it is the rear brakes. I feel a vibration in the brake pedal that goes along with the knocking sound. I'm thinking it is worn brake shoes but I won't know until I pull the wheel.

Rear upper control arm "BALLJOINT"

Rear upper control arm "BALLJOINT"

If this is the case why doesn't it do it at higher speeds?

BTW I pulled my wheels and the brake cylinder is leaking, my dads buddy said that's the problem because it glazed the pads and now its sticking? Idk but i'll def. get it fixed.(the cylinder that is)

If it's the ball joint and it fails, the wheel will fall off the car and take lots of stuff with it when it goes. Please check it straightaway.

Is this the ball joint you guys are talking about? I'll take a look at it today

[Oldblueaccord]

YES!

It will show up loose at the joint with rocking the tire off the ground at the 12 and 6 position.

Also your rear tires may appear cupped on the outside.

Well I pulled my tires again and there is a little play in the passanger side control arm so thats gonna get fixed....but I asked my local mechanic who knows what he is talking about and said the knocking is in the brakes so maybe it's the wheel cylinder doing it?

I'm gonna buy 2 new control arms just for piece of mind and let my mechanic put the wheel cylinder on, I don't want to f with anything involving brake fluid

P.S. I did hop the curb recently maybe that put the nail in the coffin for the bushing....my tires are fairly new so I can't see any abnormal wear.

Will I need a puller or a press to put these in? Don't feel like taking it anywhere seems like such a simple job.

That one you have pictured is all one piece so its just a bolt and go. You have to knock the tie rod end out of the taper in the control arm with a hammer or use a pickle fork.

The other arms were talking about in the suspension section need the ball joint pressed in. Although its a very light press fit. The a snap ring holds it in place. Nice about them is the ball joint itself is replaceable and generally cheaper then the whole arm.

Just for another idea see if your sway bar is loose on its mounts on the rear if you have one. and heck make sure you spare tire is screwed in as well in the wheel well.
