same hubs???

[Lewis82]

Got leather interior from an 03 w203 that looked like it had done v little mileage before being in scrapyard for parts and its been suggested that instead of getting new bearings as we cant fit them, that we get the entire hubs off the scrapped car with discs (as my discs are making a squealing noise for some reason) and fit them ourselves. Question is, would the petrol (I think c180kompressor) hubs and discs be the same as my c220 cdi's? Thanks for any help

Bearing kits from Mercedes are really cheap, and come with all the bits that you need.

Used discs might be a false economy too.

I'd bet on the hubs being the same, and probably the discs as well. However, if it's just brake squeal you have, you do not need new hubs anyway, just new discs.

Brake squeal is caused by the pads vibrating in the calipers, nothing to do with the hubs.

If the pads and discs are in reasonable condition, i.e. don't need replacing, take the pads out and apply a thin smear of copper grease to the metal back of the pads and a small amount to the guides in the calipers where the pads fit. This acts as a damping agent and stops any vibration.

Be careful not to get any grease on the face of the pads or the discs though.
It may also help to rub the braking surface side of the pads with some emery cloth to remove and possible glaze.

While you have it jacked up, check the wheel bearing for any play by holding the wheel at the twelve o'clock position with one hand and at six o'clock with the other and then pull with one hand, push with the other and alternate the push pull motion. If there is any movement felt the bearings can be adjusted as they are taper type. You can find excellent videos on YouTube with instructions how to adjust Mercedes wheel bearings.

The bearings were an advisory an definately have a little play. Was lookin at hubs off a low mileage car as its easier to change hubs an keep those bearings in than change bearings themselves (so my friends father says) an as we're limited to side of road/driveway repairs, the easier the better.

I should have taken a pic of the disc as its got one odd small circular patch no bigger than tip of ur little finger, thats rough. Its not smooth lile the rest of the braking surface. As for greasing the back of the pads, good idea. We never removed anything other than the wheel to get a look. May have to just attempt the bearings when my handy mate has time and grease the pads. If its the disc and nothing to do with the pad I'll just have to get new discs too. The noise is beginning to get unbearable now.

If you drive stop start most of the time, take your car out and go crazy with braking to remove the glazing that stop start driving creates. Then see if you need anything. Of course the lining to a pad may have come away and is metal on metal, so don't keep going crazy if the noise hasn't stopped within say a minute or two of hard on and hard off brake stabbing.

I took it into garage other day. Apparently the bearings are adjustable and although borderline, have been tightened up. Was advised it needs tracking, discs and pads (there's a lip round edge of disc i was told not to file, just change them) and theres a sticking bottom bakl joint which comes aa a complete arm i think they said. Unfortunately 273 quid to change to bottom arms wont be happening, I'll look elsewhere first
