Re: Radlagerwechsel vorn selber möglich?

Als Antwort auf: Radlagerwechsel vorn selber möglich? von Torsten oo==00==oo am 10. April 2007 17:09:12:

Hi,
ich hatte an meinem eta bevor ich ihn stillgelegt habe im letzten Jahr, stärkerwerdende Geräusche an der Vorderachse, die auf verschlissene Radlager hindeuten.
An die Bremsen muß ich eh dran, mindestens Beläge neu, und dann wären die Radlager ein Abwasch.
Bin allerdings kein Profischrauber und wollte mal fragen, wer soetwas schon mal daheim gemacht hat, und was an Werkzeug gebraucht wird?
Rangierwagenheber und Unterstellböcke, sowie Ratschenkasten, Drehmomentschlüssel und vieles andere sind vorhanden.
Abzieher oder sowas fehlt noch...
Wer hat Tips?
Viele Grüße
Torsten, der bald wieder Eta fahren will...

1. First, lift the car on the side you want to work on. Install jackstands.
2. Remove the wheel then the dust cap with pliers.

If you have 850i brakes, you won't be able to use your spare 15" rim for more leverage so remove the brakes now...

2. Bend the staked part of the collar nut back.
3. Install the wheel back and lower the car to the ground.
Use your 46mm socket, T bar and a 1 meter bar if you want more leverage and LOOSEN (do not remove) the big nut.

5. Lift the car again, remove the wheel and the 46mm nut. Pull the wheel hub out. Gentle blows with a rubber hammer on the outside help. If nothing moves, use a puller.

6. If the inner race the inner race remains on the stub axle, simply tap around the edge of the race with a hammer and cold chisel, or use pliers and WD40. It is easier to get it out if you remove the big brake dust shield (held in place with 3 x 10mm screws)
7. Remove the dust protection collar (yellow piece on the left picture) and clean the stub axle.

7. Insert the new dust protection collar, then insert gently the new hub bearing. If it is hard to insert, use a piece of hood and tap with your rubber hammer, until it is fully inserted. You can also use a pressing tool if you have one.

9. If you have 850i brakes don't forget that the 15" rim doesn't fit under the brakes.
10. Install the brakes, the rim then lower the car to the ground. Torque the big nut to 214ft-lb (290 Nm).
11. Stake the nut to the axle.
12. Install the new dust cap on.
