c class problem

[mitchel]

hi i recently got a 53 reg c c lass 180 kompressor and it is making a kind of scraping noise from the front passenger wheel area,iv changed discs,pads,and cleaned and inspected calipers and it has made no difference,it only does it at low speeds and is worse when i turn right and seems to stop if i turn left,any help would be great thanks mitchel

I had that same sound from the drivers side front, I deglazed the pads, cleaned and checked calipers and put back together with some coppaslip, and that cured it.
Did you use coppaslip? or put back together dry?

 

[mitchel]

hi thanks for the reply yes i put coppaslip on the back of pads and cleaned clips etc up,still made no difference,its not a brake squeaking sound more of a metal scraping noise gets wore when i turn right or press brakes

Spring

... is it a broken spring causing the front end to 'drop' I have seen a number of posts on here reporting such, just thought.

 

[mitchel]

thanks,the springs seem ok will check them out just incase

 

[mercmadjim]

Left hand wheel bearing??

 

[Cosworth]

Are your tyres and tracking ok?

 

[mitchel]

thanks for the replys guys had car on ramps today springs are fine the driver side lower front ball joint arm,steel one,the rubber bush in that looks as if it is coming out,does anyone know if this would be causing my problem and also can the bush be replaced on its own,and is it a difficult job to do

 

[mercmadjim]

I am pretty sure someone on these forums had bushes (anti roll bar i think) that did what you described, I will see if i can find it.

This was it, ball joint??

Had this with my C240, trouble is you cannot jack the front of the car up to check as the suspension and wheel fall away. My problem turned out to be the RH tyre scraping on the plastic inner wheel arch cover which had slightly come away. With the car on the ground, turn the wheels to the right and check if the RH tyre is touching anywhere on the arch cover and also check the metal splash guard on the back of the discs. Just a thought

silly tin splashguard was my thought too

 

[mitchel]

thanks for the help guys,will get a new ball joint and fit that,do i need to do the both of them either side or can i replace just the faulty one?

 

[mitchel]

hi iv changed the balljoint but noise still there,checked the wheel bearing but could only check the 2 parts i could get out,is there another 2 parts of the bearing?its definetly from the front passenger side,and is worse on braking and at low speed,also turning right,really driving me crazy!is there any belts or anything that could be making this noise?

A spring broken maybe or roll bar rubber & link

 

[mitchel]

thanks for the reply malcolm what is the best way to check the spring would i have to remove it,where is the roll bar on the front just so as i know what to check

 

[television]

The links 50 and the rubbers 20 and 70 could cause a clonk, best to lever them to check with a bar.

The springs if broken will be the last 2" to 3"and could be top or bottom

 

[mitchel]

thanks will check them out,just really anoying as its like a metal scraping noise and when i jack car up no noise as it sounds like something rubbing on the metal dust sheild behind the caliper but no sign of anything,and should the front pads have a groove at the front edge of them?

If you had the bearing down on the wheel,how did you set it up again

 

[mitchel]

i could only get 2 parts of it out and they looked ok,think i put them in the same as i took them out,so as they were kind of flush,and tightened the nut until i felt resistance then turn it back quarter of a turn whilst turning the disc,would i be able to check the other parts of the bearing as i didnt get them out
