Front Wheel bearing replacement

After diagnostics, I need to replace my front wheel bearings. Parts at hand. I read a posting by G-AMG on http://www.benzworld.org/forums/w210...free-play.html.

Does anyone have a link on how to remove the bearings and reinstall? Once I remove the dust cap, is that the access point of do I have to remove the calipers? any advice appreciated. I will change both sides to be on the safe side.

To access the inner bearing, the caliper must be removed.

This is all I have access now and hope you find it useful.

You use a screw driver to pry out the dust cap. The "official" tool is a slide hammer, I think.

A very large pair of channel-lock pliers works well on the dust cap, if you're having trouble with the screwdriver trick.

Front Wheel Bearing Replacement with pics

OK, here we go. After 2hours, 15 Minutes, I changed my front wheel bearings.

The are 3 scenarios:

a. Bad bearings- need replacement
b. Loose bearing nut, need adjustment
c. Repacking of bearings

In my case I decided to replace the bearings anyway although I only needed tightening. In all cases ensure you ensure all parts are clean and are genuine MB parts. This is not a hard job but a bit messy. Most importantly observe all safety precautions.

1. Orders the parts-correct part numbers. Bearings(2 per side-inner and outer). The bearing pack from autozone comes with dust cap, seal,rotor nut etc. Parts cost $50 for both front wheels.
2. Buy correct grease from local MB dealer- $8.99 a tube
3. Tools required- screw driver, plastic hammer, 17mm socket, 18mm socket to remove 2 nuts holding calipers, jack,5.5mm allen socket, etc
4. Jack up the car, take off the lug bolts using 17mm socket
5. Remove the calipers using 18mm socket- 2 bolts located at the back of the caliper then secure the calipers to ensure hoses are not strained

6. Remove the dust cap- its very tight use a screw driver to pry it off along the edges. I placed a metal object in the dust cap groove and hit it with a hammer outwards and it came off easy.
7. Remove clamping nut using allen key and remove the bolt holding the outer bearings in place.
8.Remove the outer bearing and pull the rotor/hub assembly out.
9. To remove the inner bearing use a screw driver and drive by the outer edges of the seal. Pop the seal out and the bearing comes out.
10. Take out all grease inside hub assembly. I sprayed the maf cleaner and used a rug to clan it thoroughly
11. Grease all bearings with mercedes 'green'; grease. Grease inside hub assembly as well
the shaft.
12. Turn the rotor assembly and Insert inner bearing
13. Drive in the new seal- use plastic hammer or in my case place a 2x4 across the seal and gently hit it in until it sits well
14. Insert the hub/rotor asssembly into the shaft
15. Insert outer bearing after greasing it well
16. Tighten the wheel bearing nut, quarter turn beyond hand tightening. Turn the rotor assembly to ensure it moves freely and theres is no resisistance. Hold the rotor assembly at noon and six oclok positions and rock to ensure there is no movement. There is no torgue speficied for the bearing nut, unless u use special tools to ensure you are within allowable 'play' per WIS
17. Replace the caliper(tighten two,18mm bolts)
18. Replace the dust cap. I added some grease on the cap
19. Insert the wheel, tighten to required torquee
20. Done. Ensure you clean the rotor to ensure there is no grease on the surface.

You did back it off a bit after tightening it, right? The tightening is to seat the bearings. Then it is essential to back it off to get the proper adjustment. There is supposed to be a bit of movement.

Good point. Correct, I backed it off a little bit and rocked the rotor again to ensure free movement. For lack of better tools, I used the manual 'rotor spin test'. Hope i did not overtighten.

Nice shots...I trust you packed the bearings and didn't just coat them with grease?

Something makes me think I'd like to see that grease under a UV light.

Good luck with it.
