Metal Knocking Noise from rear wheel well area

FairladyZ10PG · 09-15-2015, 12:13 PM

Hoping someone can chime in on this. I've been experiencing constant metal knocking noise from the rear wheel well area. Sounds almost like a loose bolt moving around everytime I go over bumps or at slow starts.

No, it's not the axle sound because I can hear that separately from the knocking noise lol. Axle noise is more like a click than it is a knocking noise.

Funny thing is that when it rains, the sound disappears

Like today, it was pouring and I noticed that the knocking noise was completely gone.

Can anyone (educated) guess what's causing the issue? FYI, I've already had someone tighten up all the suspension and the sound is still there.

I have that too. Got underneath and found mt rear diff bushing busted, had it replaced for $600. But the thud/clunk noise is still there. All my suspension bolts are tightened as well. I'm thinking it could be my stock rear sway end links, just ordered a new set, hoping it will solve this noise

hmmm... that's not good

Zbrah · 09-15-2015, 12:45 PM

Do you only hear it when you come to a complete stop? That's how mine is.

Several people have reported a noise from the rear that turned out to be a wheel bearing.

FairladyZ10PG · 09-15-2015, 12:50 PM

No, mine is there at low speeds and over bumpy roads. Non-existence when driving on highways at high speeds and when it rains

I'm guessing the moisture plays a certain role in getting rid of this noise

Maybe applying some grease may solve this issue but just have no idea where the noise is coming from other than it is from the rear right suspension/trunk area

Thanks for that! But their description is different than what I'm experiencing. And it's a metal knocking noise rather than clicks. The metal knocking sound is definitely from the passenger side only.

check your endlinks.

FairladyZ10PG · 09-15-2015, 01:01 PM

^would moisture or grease applied to endlinks make the sound disappear?

I don't have the clicking noise attributed to the wheel bearing, rather it's more like a "thud" sound when the vehicle come to a complete stop. I really hope it's my stock sway endlinks because I have aftermarket sways installed for a while now.

if it's the joint, then it will need to be replaced.

Which did you order?

FairladyZ10PG · 09-15-2015, 01:24 PM

Just sent email to John @ corner3garage lol

Just scheduled for install on 23rd wednesday for SPL Pro endlinks and get rid of rear axle clicking noise as well

More money more problems lol

I bought Energy Suspension endlinks from Zspeed. $90. Will have it install soon. I'll keep you updated if it solves my problem.
