Popping Noise when first accelerating (VIDEO)

weath100 · **Joined:** Mon Jun 17, 2013 6:01 pm **Posts:** 10

I get a popping noise coming from what sounds like the passenger side of my 04 Liberty. The noise appears when I first hit the accelerator (even lightly) and when I let off the accelerator. I also hear it when slowly going over curbs with my passenger rear wheel. I just installed an OME lift, but the noise was there prior to lift install now it is just more pronounced. I have a link to a video below that hopefully allows captures the noise well enough.

The jeep has 105,000 miles on her.

Any help would be appreciated.
Thanks!

Have you checked the floowing
lower ball joints
rear lower control arms ( most times they just give you a tracking issue but??)
Upper contol arm , mainly ball joint ?
Could also be a CV in front possibly

Fixed the privacy issue.
It sounds like it is coming from the rear. Could this be my rear upper control arm?

Maybe you need to tighten up your rear shock bolts.

Shock bolts are good. Could this be a bad ball joint on my rear upper control arm?
Whats a good way to check this?

I know that sound... its the rear upper control arm (that boomerang above the axle on the rear end)... or at least that's what it was on mine. get under neath it and check the ball joint and make sure the bushings and the bolts on them are still there.

IF YOU NEED AN ALL NEW UCA, DONT BUY AND AFTERMARKET THEY GO BAD IN 20K miles. spend the insane amount and buy OEM for that part TRUST ME
its about the only time OEM is better i learned.

if your interested in something more expensive...

before any purchase, make sure the part you intend to replace is the actual part broken. and not to solely rely on others opinions.

Thats a little out of my price range right now. I think I am going to stick with OEM. Yeah I am 90% sure this is the issue because the driver side bushing is shot. Even if this is not the issue I will need to replace soon as it is rusted to the point where the integrity of the steel will soon be in jeopardy.

I just purchased a used oem one from Ebay ( spaulding auto parts ) $68 shipped - it is in perfect condition, When I talked to them over the phone he stated they had at least 30 in stock.

How many miles were on the used one?

So, I just finished replacing my rear upper control arm. The noise is still there.

It happens when I first hit the gas and when I articulate the rear suspension, such as running over a small curb with one tire.

Any thoughts on what else it could be?

I just checked my U joints and my lower control arm bushings seem good. When I was checking my U joints I noticed my transfer case had a little play in it (up and down).
Could this noise be a result of a bad transmission mount?
Here are some pics of my transmission mount
