It appears that the left side rear wheel bearing is making noise and causing vibration. Only this wheel sounds and feels bad when rotating the jacked up wheel.

I have the CD manual and hae noticed a great deal of speciality tools listed for the R&R of the bearings. Isthis one of those jobs that can be performed w/o using these tools, or if not, will all of them be required?

This looks like a pretty involved repair, but I have a fair amount of DIY experience and mechanical knowledge. Is this a repair that can be completed in one weekend?

P.S. I searched the archives and only found references to 300D regarding rear wheel bearings.

best bet, pull the trailing arm, take it to dealer for repair.

I have the same problem on my 82 126, but I can't seem to get the bolts off the trailing arms - anyone have suggestions? My Air impact can't even budge it.
Thanks

If it's a dual row ball bearing, you can r & r it with a hydraulic press or the proper bearing removal/installation tool. The tool will cost at least $180-$200 or more.

If it's a dual row roller bearing, you can't do it by yourself. You need the special MB tools. Entrust the repair to a good MB shop.

Before you disassemble it, check with the shop to make sure they'll work on it off the car. Many shops these days, especially dealers, won't do bench work for liability reasons.

i just had same prob with my 1991 126 model. Even the M/B dealer wouldnt do the job mostly because they didnt have the special tools. Best to buy a used control arm complete with hub. I just did that from great forum member who was parting out cars. If you can get an Arm & Hub and know how to use a spring compressor, you can do it yourself. It will take you about 8 hrs. Contact "jim16671836" on this forum as he may have part you need. I believe he is in Indiana.

I totlly agree, it's not a DIY job.
I have tackled just about everything on my 126, but couldn't whip that rear bearing.
I went so far as to buy the big "castle nut" socket that is required to loosen the bearing retainer. With an 18 in" breakover bar and a 3ft cheater, and two of us big guys hanging on the end - we couldn't budge that retainer nut.
My big impact just bounced off also.
