|VW Golf Mk2 With New Wheel Bearing Fitted.|
Car: 1991 VW Golf Mk2 1.8 Driver
At the time of replacing the Wishbones, Bushes, Anti-Roll Bar Links, outer CV Joints & the Front Brake Discs and Pads, we did think we could get away without replacing the front Wheel Bearings for a few months.
Well ...just a few months later and 1 of the front wheel Bearings decided to call it a day! Noise was again coming from up from the wheel area, but when we got out and tried to shake the wheel, we could do just that!
It was obvious the bearing was about to fail completely, so it was time to park the car up, and order some new ones.
When removing the wheel bearings on a car fitted with alloy wheels, you first need to jack the car up, just to remove the center cap from the wheel, and to also knock the indentation in the wheel hub retention nut back outward, before re-fitting the wheel and lowering the car back down so that you have the weight of the vehicle on the wheel so that you can undo the retaining nut.
Undoing the retaining nut is never easy! It takes a very long strongarm bar. Sometimes somebody's foot may need to be on the brake pedal as it can take a lot of force to crack this nut! (which can sometimes shift the car!) At other times you may find it takes two to lever it, with one person just pushing in on the socket to prevent it slipping off the nut. Sometimes you may even need to stand on the bar. Having taken these nuts off recently though, this time it did not zap all our strength completely like it normally would!
OK, jacked up (& supported) for the second time, now that the retaining bolt has been removed.
We removed the brake disc and pads, and undid the suspension strut bolts, and popped out the CV. These all came apart easy, having been fitted only recently.
Where we were expecting a problem was with the Ball Joint, trying to undo the retaining nut on the bottom of a ball joint without turning the shaft is almost impossible, but doing so makes thing much easier.
As normal though the shaft began to rotate too, before the nut could be removed!
Moving the nut back and forth on the oil soaked threads and keeping pressure on the ball joint to prevent the shaft spinning, 10 minutes later we still could not manage to remove the nut, and so we used a nut splitter to break the nut off the shaft!
Had we not managed it that way, we would have had to use mole grips on the shaft which would have ruined it, and that would mean fitting a new ball joint, this way we would just be re-using the old one again (together with a new nut).
Here is the back of the wheel hub, the wheel bearing seems to have a large circlip holding it in. As our small circlip pliers were not going to be up to removing this circlip, we took it to somebody with garage equipment that would be able to remove this wheel bearing and fit our new one.
Luckily in our spare nuts box, we found one that was a perfect fit for the ball joint.
We got our wheel hub back with the new bearing pressed in.
That old bearing was dry and knackered!
Just as tricky as removing a nut from the ball joint without the shaft spinning, is refitting a nut without the shaft spinning! Fortunately we managed it this time! (with a couple of taps with a hammer!)
Although it can all be refitted, that retaining nut should be tightened up fully once the wheel is on.
With the brakes back in place and the wheel back on the ground it's time for the strong arm bar to do it's job again. Then just knock an indentation back in on the retaining nut to prevent it from coming undone.
Finally that center cap can be popped back in.
