Hi, another post from me to all DIY-ers.
I did my front wheel bearings. Job is quite straightforward. Specially if you decide to buy already built up hub with bearings installed. But you can also but repair kit and save yourself some £'s. Hopefully after reading this post you will save
. I had 3 approaches.
Here is what to look for:
When you building hub back together, see if you can find someone with press rather than do it cowboys way if you can't, than you can do it with hammer but go very steady and use old bearing as a "transfer plate"
When you manage to install new bearings In the hub and all you have left to add is oil seal/abs magnetic ring. Again be careful and what is most important do not push it all way back to the bearing. See picture attached. This is how it should look. For some reason the way hub was made it allows to push seal further down. And that can cause you new problem. As I said this seal is also hall effect magnetic ring for speed sensor.if pushed too far. As soon as you set of, ESP/ABS malfunction message will appear in dash as sensor can not detect how fast this wheel is spinning.
Apply as much grease as possible, people say to only use green one from MB. I'm not sure if this makes difference, as long as you use good amount and quality bearing grease.
There is a correct procedure to adjust how tight locknut has to be on YT. But sometimes we don't have necessarily tools.
According to ex mercedes mechanic, if you don't have DTI. You need to tighten lock nut by hand to the point that wheel will not easily spin. Than back it of 1/4 turn. Recheck it after about 1000miles.
I did exactly that and car runs well.
Hope this will help one day
