S124 Rear Wheel Bearing

[tonychunk]

HI

My trusty old S124 has a noisy OSR wheel bearing in need of replacement.

I usually do my own jobs, but my health has restricted what I can do now.

Can anyone recommend a place or even a keen DIYer that can do this job?

Many thanks

Mercland in Nuneaton. Jay has a good reputation.

For a non-MB specialist I can also recommend Danny at RSD in Daventry - he does any work for me that I can't /won't do.

Thank you for the reply on tis.

Has anyone had experience of this tool?

 

[LostKiwi]

Interesting, but how do you get the hub back in?

 

[tonychunk]

The kit comes with adaptor plates and sleeve. The force screw is then used with adaptor plates and sleeve to remove bearing and to insert new one. Then adaptor and force screw to fit hub

 

[LostKiwi]

Looks pretty useful then. Link?

 

[tonychunk]

What link did you need?

I have managed to buy one second hand this evening.

Nearly the same amount of work as taking the hub off as you have to remove the drive shaft.

Not on a 129 where the drive shaft bolts on at the diff end.

yes like lots of other mercs but I thought the op had a 124?

Fair point. I'd guess the benefit is in being able to do it at home instead of taking the hub to someone to press the bearings in/out.

I have read this is one of the most difficult jobs to do on these cars. Lots of write ups, the main problem quoted as being removal of the hub. There is also opinion that even with removal of the bearing carrier it is not possible to press out the hub and bearing without destroying the back plate. If any of this is correct I don't know as I have not experienced this job on this model.

I was quoted £300 in labour then bearing cost on top for bearing replacement is this about the going rate?

Tad high but it’s a bit of an unknown time, that bearing most probably been in there since new, so everything is either tight or corroded.

UPDATE.

Pleased to report it's job done.

The puller arrived, obtained for a very respectable price from an auction site.

A little apprehensive about doing this job after all I had read on the www.

The easy bits (drive shaft, disc, caliper, parking brake assembly) out of the way it was tool try out time.

As expected the hub was very very tight! ..lots of grease applied to forcing screw, a large breaker bar and some help from a scaffold pole process was slow but it moved smoothly and finally the bang that meant it was well on its way out. A few more turns and out it popped.

A little battle with the circlip, but it came out. The bearing was also very tight, but again with the help of the breaker bar and scaffold pole it came out easily enough.

A good clean of the bearing carrier a little lube and pressing the bearing in was all good. I had placed the new circlip on the hub so as not to make that fatal error of missing it! I compressed the circlip in a vice and used some small circlip pliers to hold it closed. Released it from the vice and popped it in.

Next I assembled the parking brake, simple without the hub there. I pressed in the hub, which was an easy task.

The simple reassembly of the other removed parts and she was sitting on the ground. Road test and all is good.

Very pleased with the Sirb90 (it has everything in the kit needed to remove and install the hub and bearing) a great bit of kit.

Do you mind me asking which replacement bearing you bought, did you go genuine or aftermarket?

Well done by the way, that's meant to be a really nasty job!

Hi Mathew.

Thank you for your kind words.

I used a Febi bearing that I got at a bargain £10. My thought process was that if I went wrong and I had to pay to have the job done, I would maybe buy a genuine one (£110). Now I have this tool I would do this job again without hesitation.

Nice to know, I've had only good experiences with Febi parts, I'll probably buy there arms for the front of my car.

That bang signifying the bearing was on it's way must have been V satisfying, I'm lead to believe as well as being a V tight fit on the wagon they're also glued in!!!!

** Anyone who needs to do rear bearings on 124 or similar message me, the tool is here to be used!

Matthew...I have only had good experiences with Febi too and yes the bang was very satisfying!
