Hi guys,

I searched about this issue but couldn't find it.

I had CLK 320 convertible with stock 16 wheels (No sports package)

I just changed to 19x8.5/19x9.5 with Toyos 235/35 19 on the front and

265/30 19 on the rear.

After the installation at Firestone, the mechanic said there's a weird sound

coming from the rear but he couldn't locate it. There's no rubbing or anything

When I go back and forth and when it rotates, I hear metal scratching sound

like, 'click, click'

I checked everything. I used shorter lug bolts than the stock one. Didn't see

any rubbing on the rear. Checked on brakes too. Mechanic said it's either

wheel bearing problem or computer problem.

I really don't understand. With those stock wheels, I didn't hear anything. But

suddenly, I just changed to bigger wheels and tires, and I hear this annoying

sound

Dealer will solve everything but it's too far away from here. I don't want to

drive this on the highway.

Then what stores I need to go? Body shop? Tire shop?

These Firestone guys are definately helpless.

Sorry for my poor English...I tried to describe well but it's too hard

Please help me!

it's the longer bolts rubbing against the emergency brake.

remove the wheel, stick the bolt in and see how far it goes through. it should come out about 1". any more than that and it'll hit the emergency brake.

TigerJK

Thanks for the quick reply. It really makes sense. But mechanic said those new bolts are shorter than the stock one, so there's no way bolts are hitting something. Well, I'll double check tomorrow.

If it's hitting the emergency brake, is it ok to drive for now? I'm just too scared to drive. I don't want to break anything.

If the mechanic were so smart he'd have figure out the clicking sound now wouldn't he?

This clicking sound only happens when you drive? If you drive faster, does it click faster?

TigerJK

Yeap. Clicking sound only happens when I drive. If I drive faster, it clicks

faster.

They removed the rear wheels and pushed the pedal. Then I didn't hear

anything. So it must be something with wheels and bolts.

I'll check it tomorrow. I hope nothing happens when I drive..

Thx!

even though the bolts may be shorter than stock ones, the stock rims might be thicker.

TigerJK

You're right. So what can I do to prevent the sound?
Get a shorter bolts? or spacers?
Any suggestions?

henry47

what you can do is fix it right now if you want. If you have a dremel, you can just sand down the bolts to the correct length.

The minimum mercedes recommends to tighten the bolt is 6 full turns I believe. Anything more than that is not necessary. Sand down the bolts until you can get 6 full turns before you feel the torque.

+1 same thing happened to me. The shorter bolts fixed the problem

i used to have something like this as well.. some weird sound coming from the back.. when i get it check its the sway bolt louse...

TigerJK

I drove again in this morning and came home.

I was surprised that I could not hear any noises!!

What a surprise! Really quiet as usual

I will drive more later and if I hear again, I'll go and fix it.

Thanks a lot guys!

By the way, I really like this wheel. I must do something with rotors and

calipers. I didn't notice before but they look so ugly now!

dynomite05

And slam her down

TigerJK

Yes! Definately will lower it. But I need to get a bodykit first

dynomite05

I will have some H&R springs available in about a week or so. They only have 8k miles on them. Let me know if your interested

astropat

Did you upgrade?

dynomite05

Switching to Vogtlands. Hope they will be a bit more comfortable

astropat

Word. I can't wait to throw on my PSS9's.

dynomite05

I was thinking about getting them also, but I am going to leave that for next year.
