Could this be it?
I believe this means bad wheel bearing...but how bad would you say it seems based on this video? Should be safe to drive for another week until I can order the bearings and grease right?

you dont need to order and wait, you can buy the bearings, seals and grease at AZ, NAPA etc.

btw - that is a loose bearing. This much slop can also cause the wheel to scrub a bit in tighter turns at slow speed. You will also feel that your brake pedal acts different in some situations.

I'd rather not get cheap parts. Been there done that. Never again. I'd rather take the risk on worn OE parts than put Chinese garbage in that will break without notice.

I only need to drive the car once more this week so it'll be fine. Will report back Saturday with some photos!

You should also do that same exact test on the other side too. See if it gives the same feedback.

you can get SKF, National or Timken - National and timken are very good quality. The SKF is available from NAPA and are french.

both my cars have japanese NTN bearings in them - and both looked like they were spinning in extremely spent out green bearing grease, I did read that MB installed japanese bearings in the mid to late 90s.


Im not trying to advertise anything - but wheel bearings are one thing on my checklist that should always be top notch. I have had a bad experience once a long time ago.

I was unaware I could get SKF at NAPA...Either way the parts arrive tomorrow and I'm set.

Non. SKF is ultimately Swedish https://en.m.wikipedia.org/wiki/SKF

Yes I know they are swedish, the ones you buy at NAPA say made in France.

I usually order these wheel bearings on amazon just as preventive maintenance, Last I ordered set 12 and 17 timken for under 12 dollars a pair. - Made in USA items. You can buy the same from orielly auto etc. but they sell them for slightly higher price.

I usually buy the above 3 brands (good experience with them) - my car's driveshaft even uses an SKF bearing, it was a skateboard wheel size - but I bought it from a bearing sales business.

Heres with the hub off...pretty speedy. 30mins to get it off.

Does this scoring/discolor look typical for a spindle?
I ran my finger over it and it feels smooth, so I think its ok right? Want to double check since this is my first time doing this on any car.











I have not torn apart the hub yet, I tried removing the rear seal and it wouldn't come out with a screwdriver so I'm buying a seal puller tomorrow to help.

you dont need a seal puller, get a socket that sits on the inner bearing cage, and use a hammer to push the bearing and seal out together.

You can also use a punch to crush the seal and lever it out,

btw - this yellow grease is not the factory MB stuff, maybe someone packed with new grease. Doesnt matter as long as its disc brake wheel bearing grease.

When you remove the bearings, touch the grease near the rollers and then look at it in strong light, if you see glitter - then the bearing is toast.

can you run your fingernail on the scratched part of the spindle to see if the scratches catch your nail?

Finished up today. Everything went well, but the car still pulls. Obviously it needed to be done, but was not the issue.

I'm kinda out of ideas here. What diagnosis can I try to figure out what part is causing the pull?

Remove the rotor and brake pads and swap them to the other side.

ps2cho, have you confirmed that the right front caliper releases completely (is not sticking) when the brake pedal is not pressed?

Lift the front of the car, and spin the front wheels, they should spin freely. Count how many revolutions each wheel makes after you spin it the same speed.

If OK, press on brakes, release, now repeat the above test.

I don't understand what this may prove, especially if the problem may only be present while the car is actually on the ground, but I do agree with you about him testing both wheels. Testing two things that should perform identical is the best way to isolate the problem.
