Just wanted to say thank you for your video! I'm doing my bearings and rotors on my W126, and having your example as a reference has been super helpful.
Hey just wanted to say thank you. Just completed all new rotors, pads, shocks, bearings on my 1990 420sel. Watched, studied and followed your vids. Thanks for making it possible!!!!
Thank you for making this video. It helped me realize I can do this myself. I watched a couple other videos and resigned to thinking I would just take it to somebody who had the right tools. After watching you do it and your methods I am confident I can do it. 1986 300SDL
nicely done with some nifty tricks like using the old races. Lots of forum discussion on whether to use a dial indicator or not. Some do, some don't mercedses does. I think I will try both methods. I have always done it old school like IM does here. One thing is certain. Too tight on the spindle nut is bearing failure.
Your channel is a godsend. I just started tearing down to do the front steering and suspension, and decided to do bearings and rotors while I'm in there just because. Nice to know the hub and rotor bolt together like that. I was trippin trying to look for parts lol.
In the video I stated that I packed some extra grease down in the hub before inserting the outer bearing. There is really no need to do this. There is no advantage in having extra grease inside the hub BETWEEN the inner and outer bearings. Also putting extra grease in the dust cap is useless as well. LOL..... No need to do this either.
Showing how to adjust a steering box correctly would be another good video. Few people seems to know how anymore and buy new/rebuilt ones, when being adjusted properly is often all that's needed.
@@ImpalamansGarage -- When I bought my '84 manual-trans Benz 240d, the steering was so sloppy, and it was so slow, that other people wouldn't buy it. I immediately adjusted the steering box (on benzes the adjusting screw gets turned out to tighten, unlike every other manufacturer), and after adjusting the valves and replacing both fuel filters and air filter under the hood, it was like a different car. Fuel tank screen is next.
You can pick up a small one at harbor freight for a reasonable price. It's fine for occassional use but for every day work a better quality one is needed.
That spindal nut was so tight on the threads on my 85 300d that I had a hard time turning it off and back on even with the lock bolt loosened. I ended up overtightening it after replacing the bearings and eventually after a few months I burned up the bearings and swole the hub on the left side but managed to sve the right side, and had to replace the whole left assembly. Wish I had never thought about replacing the bearings when doing the brakes.
On most cars an initial tightening followed by backing off and hand tightening works well. If your locking nut was difficult to remove, you can pry it open just a little with a screw driver since it has a split in it. The mercedes manual says there is supposed to be a little end play although I cannot recall what it is without looking it up.
@@ImpalamansGarage I actually tried that and it is so solid on the 85 that it would not budge. It looked like a pretty solid block of steel that had been machined. The main problem of course was me simply overtightening it. I don't know what possessed me to keep cranking it down on the spindle. Oh well. I no longer have that car but actually wish I did. It had a lot of miles on it but I had fixed it up and it ran like a top.
Great job. I'm about ready to change my bearings. Two questions. When you are punching out the races. How do you make sure you don't kink the hub wall? Also do you put grease on the whole inside of the hub, where the races sit and else where? Thanks much...
If you slip and nick the inside of the hub with the punch, really it's of no concern. Nothing that is moving touches that part. But be careful nonetheless. Sloppy work is sloppy work. LOL Use a flat-ended punch. This old fashioned method of removing a race can be done on all makes of car. Really there is no reason to pack the hub full of grease in the void between the two bearings. If you put too much in there, as heat builds the grease will ooze out of the dust cap and make a mess on you wheel. It won't hurt anything but it will make a big mess as you drive. Just put a moderate amount in there. Of course pack your bearings well. That is the most important part.
@@ImpalamansGarage I guess the reason could be if the bearing failed and got stock the race would not turn and damage the hub. But in this case it would probably turn on the spindle, not sure which one is worst...
A bearing race is a press fit but it's not THAT tight. If it were you'd need a press. In retrospect I think applying a film of grease before installing the race really does little if any good. Sometimes a race will spin in the bore and I think that is caused by either corrosion or heat.
When a race does spin, you have to stake the inside of the bore prior to installing the new race. This happened to my right rear wheel on this car. I made a video on replacing it and I staked the bore and also used a compound to help keep the new race in place. Check out the rear wheel bearing video. That one was a challenge.
The part numbers are in the video description. I use fcpeuro, pelican, autohausaz, rmeuropean, ecs tuning and parts geek mostly. One of those usually has what I want.
@@ImpalamansGarage Thank you. I think I will continue with it as it is (flush) because I've also come across directions for this job that say to tap it in evenly till it is seated all the way (or bottomed out) and there isn't any mention of it needing to be up to an 1/8th inch above the lip of the hub. I hope I'm not screwing this up. First timer.
I was expecting mine to be flush actually but I bottomed out everything and the seal was still slightly up. It will work fine as long nothing is cockeyed. That would be bad! lol
Well I suppose it depends on what you mean by a "hum". When you turn the brake disk the amount of noise you should hear should be analogous to lightly rubbing your hand over your T shirt. I would not categorize this as a "hum" however. More like a rush of air. If you hear a low pitched hum, i would say they are too tight.

Go slowly. If you're not sure about something, research the issue and ask questions.

Using the old race to drive in the new one is old-school smarts :)
Works on Chevys. Why not Mercedes. LOL

Agree. Good idea foe a new video!

Great video! Relieved not to use a press...dont have one anyway.

Top notch quality work!!! Definitely will use this video when I need to do mine.
Thanks boss. Big help. Too many videos talking about a dial gauge. Sometimes a hoss doesnt have time for that shit.

excellent again and again. Tnx.
Video Well Explained thanks very much
Cool! Thanks for stopping by!
Thank you!
Thanks!

@@ImpalamansGarage Thanks the reason I asked, is some people say install races first (no grease), then grease bearing and race and hub...

Where did you order the new brake wear indicator cable from, and the new soft brake lines?
The part numbers are in the video description. I use fcpeuro, pelican, autohausaz, rmeuropean, ecs tuning and parts geek mostly. One of those usually has what I want.
Did you make a video of replacing the rear wheel bearings on your Benz wagon? I looked through your videos and didn't see it.
No I left those alone. Hopefully it will not come back to bite me later!
What happens if the seal goes in and is flush with the hub? Mine bottomed out flush with the hub. Should I continue? Help!
Well every car is a little different to a degree. I would stop where you are and continue with your work.
@@ImpalamansGarage Thank you.

@@bmpvw Yeah just follow the directions. No worries.

@@ImpalamansGarage Ok good, it's definitely not cockeyed...it's in there evenly all around ..just flush. Thanks again!
cool
I have just done my front bearings when i spin the disk i get a very slight hum i s this normal

@@ImpalamansGarage yes its a light sound even if i loosen the nut the sound is still there when i spin the disc
I got a baring a race tool from Harbor Freight
That will work just fine.
