    Hello,
    I have had my CLS 500 almost 2 years now and it is a joy to drive and hands down the best car I have owned. So I thought I would start a member’s thread.
    Soon after purchasing the car I had a major service and thorough inspection carried out by a local specialist, he gave the car a clean bill of health and the only points mentioned were that a non-genuine lower ball joint had been fitted to one side only prior to my ownership, an exhaust bracket required welding back on and a parking sensor wasn’t working. The ball joint was not causing any issues but I decided to buy 2 new genuine ball joints to fit in the future.
    I have finally got around to fitting them and I decided to fit new front discs and pads as the front pads looked a little low and the discs were always slightly rippled and it did bug me a bit.
    So with a bit of nice weather today I decided to fit the new parts! Unfortunately I have not managed to complete the job today, More parts required!!! But I reckon I have found out why the discs were rippled and prevented a possible disaster!

    Here’s a little write up of today’s antics! Replacing the lower ball joint on a W219. Thought it may be of help to anyone wanting to do the job at home.

    Remove wheel and knock out pins on caliper.

    Unbolt caliper and remove, remove pads.
    - [​IMG]
    That doesn’t look right! Wearing on one side only by the looks of it!!
    - [​IMG]
    That will be the corroded and seized calipers then! Seals perished, chrome on pistions flaking off, pistons corroded and seizing. Runners for pads corroded and pads tight.

    :fail
    SO……..A few quotes for caliper re-fub from a few companies. Looking at around £200 +VAT per caliper and a week lead time. Rang Mercedes Leeds to get a price out of curiosity and I was pleasantly surprised! With 10% discount for being in the MBOC, 2 x Calipers and 2 x New flexible hoses came in at £483 Icluding VAT. They will be here on Saturday!

    So nipped out to pay for those and carried on with the ball joint when I go home.
    Remove disc. Hang caliper out of the way.
    -[​IMG]
    Undo and remove speed sensor.
    -[​IMG]
    Undo ball joint nut and separate with scissor type ball joint separator.
    - [​IMG]
    Push out ball joint using special tool. This was bought on an internet auction site for less than £40.
    -[​IMG]
    Push in new ball joint.
    -[​IMG]
    Voila!!New genuine ball joint in place! Once joint in place, Nut was tightened to 50Nm plus 60 degrees as stated on WIS.

    Now wait until Saturday to fit new caliper, disc and pads and do it all again on the other side!
    I will update in due course!

    My shiny new calipers are here!
    However I have not been able to fit them just yet due to me been struck down with the man flu! I did manage to get the other ball joint fitted and both sides built up with new discs ready though. Hopefully they will get fitted tomorrow if I feel any better.

    Thanks!
    Feeling better today so fitted the new calipers and new pads, all looking very good now. Car needs a good clean though now!
    A few more pictures of the steps taken:

    [​IMG]
    Screw the hoses onto the caliper and apply a little grease to threads on bleed nipple also.

    [​IMG]
    Make sure the pads are in the correct way. The little arrows indicate direction of travel.

    [​IMG]
    Fit caliper and tighten bolts to 180NM as per WIS. Then disconnect hose and remove old caliper. Connect new hose. Slip in the pads with a little copperslip on the backs and guides, new spring and pins driven through.

    [​IMG]
    Do same on drivers side but remember to replace wear sensor wire on this side.
    Bleed each caliper ensuring no air left in the system and pedal is nice and firm. Top up brake fluid if required.

    [​IMG]
    Re-fit wheels, WIS states 130NM for wheel bolts!All done!
    Needs a clean! :bannana:

    Been for a test drive to try bed the pads in a little bit. No vibrations under braking at all which is good!
    I did notice the steering to be quite a lot lighter too, the ball joints made quite a difference I think. I had a look at the old ones when I got back out of curiosity and split the rubber off them. One of them was quite dry and rusty looking inside, the other still greased and smooth. So worthwhile after all.

    Good job and thanks for the pictures. Im suprised how corroded that caliper was for a 2007!

    Also never knew about the arrow on the pads :thumb:

    I was surprised also how corroded the caliper pistons were. It looks like the pistons themselves are aluminium with some plating on them, possibly chrome.
    They aren't worth getting re-furbished really either as new ones are just as cheap from MB.

    New Wheels and Tyres

    I Bbught myself some 18" CLS amg iv's a while back as a spare set so I could get my 19" amg iii's refurbed as they were looking a bit tired.

    I decided to get the iv's powder coated and get some new tyres on them anyway and run on the 18"s for a bit. Just fitted them yesterday and I am quite impressed to be honest, the ride is a bit more forgiving and the road noise has reduced considerably. I think that is probably down to the new Goodyear's more than the wheel size.

    Anyway a couple pics.
    Need new centre caps I know!
