95' E320 Wagon Rear Wheel Bearing Replacement
 

I'm sure there is a video or sticky in the forum that gives good details of how to replace 95' E320 Wagon rear wheel bearings?

Can anyone point me in the right direction!

Hello - take a look at the link below for the procedure. If you have any additional questions about the procedure, please submit a Comment just below the article and one of our techs will get back to you with details.

just a heads up.

the wagon rear wheel bearings are cartridges with taper bearings in them, they will require gargantuan force from a slide hammer or a massively strong press to remove the hub.

Once that is out you can remove the nuclear sized circlip and press out the bearing cartridge. the process is similar to the sedan but requires 10 times more force and stronger/larger tools

Thanks guys!

I have several 20 ton "H" presses so I should be OK. My immediate problem at the beginning is getting the 30 mm 12 point nut off the axles, but these links to the articles you posted have been just what I was looking for and if I have any questions I'll ask!

Kinda already said but to be clear...the width of the bearing is wider on wagons...point is to make sure you get the correct wagon bearing before pulling it apart and then finding out you have a sedan bearing.

Put a cable or large tie wrap through the bearing as a safety so it captures the large snap-ring it cases it launches loose during removal.

The job seems intimidating but is not that bad unless the car is rusty.

Put the new bearing in the freezer a couple of days before to shrink it, polish and lube the bore/hub it goes into and you should be fine. Nicer than a 123 wagon, no preloads or adjustments to make.

Good time to do rear brakes if needed.

Have thread locker on hand for reassembly.

Good luck!!!

Thanks Sugar Bear!

I see I may already have a problem, as the local parts store I bought them from told me the sedan and wagon bearings were the same! I'll have them in hand tomorrow will have to compare the two.

The confusing part is that in your model year the wagon and sedan are both E320's and their parts book may not differentiate a wagon vs. a sedan. Back up a couple of years for example to a 1991 when the 300E and the 300TE's were badged differently and it will show the difference. See if their parts book lists an S124 indicating a wagon in 1995, that should show a different bearing.

If not, I think it will work if you order a bearing for a 1991 300TE to insure getting the wagon bearing.

Good luck!!!

Gotcha!

Thanks for the heads up!

The last time I replaced rear bearings was on my 88' 300TE wagon and I'm sure when ordering this wasn't an issue as it is for my 95' E320 wagon, for the very reason you've described.

I returned bearings to the parts house this afternoon and am going to buy from Pelican instead as they do differentiate between the wagon and sedan in their part numbers!

the sedan and wagon bearings may look the same on the counter, but they are different internally and wont fit on the wrong car

Yup got it...thanks Zuliqar!

Hey!

I'm still working on replacing my rear wheel bearing on my 95' wagon and have the entire rear wheel knuckle / bearing carrier off the car.

The articles in the tech section aren't clear how to press out the bearing with an H press once it's disassembled to this point.

Do you have to remove the hub from the knuckle 1st and if so does it press out from the back or front?

Thanks

It's a complete pain. I couldn't figure out how to actually get my press in a position to do it, and wound up taking it to a machine shop and let them deal with it.

Be sure you get the rear torqued down properly so you don't destroy the new bearing once you get it in. Make sure you replace the LCA bushing while you have this off the car.

Press the hub out first, from the inside to the outside. The outer race will come off with it. Then a large snap ring has to be removed and the bearing can be pressed out the same way. The race left on the hub is easiest removed by cutting a slot in it with a cut off wheel stopping short of actually cutting into the hub. Then hit the slot with a cold chisel. The race is rather brittle and should snap apart the uncut section rather easily.

Press the new bearing in only pushing against the outer circumference. Then the snap ring... don't forget it. Press the hub into the bearing only pushing against the inner race. If you don't push against the inner race the hub can push the race out of the bearing instead of pressing into it.

All the while the backing plate will be in the way of everything and if you aren't careful you'll bend the **** out of it. The result will be contact with the rotor on reassembly as well as e-brake difficulties. If you do damage it, do yourself a favor and get a new one before reassembly.

My experience with the wagon rear bearing is the inner race comes off with the rest of the assembly.
