Megane 1, removal & reinstallation of wheel hub/wheel bearing
Don't know if this helps but I just did the front wheel bearing on my 99 Megane Sport. Here's what I noted so next time it won't take me all day.
Lump hammer, block of wood; ½” breaker bar; 30mm socket; WD-40; socket set; various spanners.
Removal & Reinstallation of wheel hub/wheel bearing:
- Before jacking up car, remove centre cover from wheel. Loosen central driveshaft hub nut slightly with 1/2” breaker bar and 30mm socket.
- Jack up car and put on jack stands.
- Remove the brake calliper (2 bolts from back side) and put out of the way. Under no circumstances should you remove the brake lines; leave these in place or you’ll have to bleed the brakes.
- Remove brake disc (2 torx head screws in front of disc); may have to tap off from behind with block of wood and lump hammer.
- Take jack from under car, leaving the car on jack stands. Put jack under shaft that controls wheel steering (left side of wheel) and jack up to put some tension on the bottom of the bracket. This will stop the ball joint from rotating allowing you to take off the nut from top of joint.
- Unbolt nut/bolt from bottom of hub and tap out (bottom ball joint); if tight, leave nut on the end of the bolt and tap it out so as not to ruin the threads.
- Free off the bottom ball joint by inserting breaker bar behind shock absorber on wishbone and prying down. This should move straight down, freeing up the bottom ball joint.
- Remove carrier bracket (2 large nuts/bolts from front of shock absorber)
- Remove ABS sensor (or if rusted, unplug it at fender well).
- Remove 30mm hub nut.
- Tap on drive shaft in with block of wood; be careful not to pull it out all the way or it will disconnect from the engine.
- Remove hub.
- Replace wheel bearing (take it to a garage and pay them to do it on a press; around £15).
- To replace hub, slide it over the drive shaft and insert the carrier bracket bolts on top of hub/shock absorber. Can finger-tighten these for now just to hold the hub in place.
- Put on 30mm hub nut and tighten enough to hold drive shaft in place (snug fit; tighten this down all the way once wheel is back on).
- Fit pry bar under wishbone and re-insert the bottom ball joint into hole; re-insert bolt & nut.
- Make sure jack is under the wheel steering strut to put some tension on; re-install in hole and tighten down top nut.
- Plug in ABS sensor.
- Reinstall brake disc and tighten down 2 torx head screws.
- Reinstall brake calliper and tighten down 2 bolts.
- Replace wheel; let down jack so car is resting on all 4 tyres.
- Tighten down hub nut all the way using ½” breaker bar and 30mm socket.
- Test drive.
