[Vwdiesel] What exactly holds the A2 front wheel hub in place? Just the b...

[Bryan Belman]

Thanks Patrick, that was more on the lines I was thinking, the G-force effects when taking corners.
It works and it is simple.  I like it.
Yes, I got a replacement Kit when I purchased the new wheel bearing from Autohaus, AZ and the 2 new circlips were given to the shop that pressed out my old bearing and installed the new one.

I should have her back on the road later this evening.

Bryan:

First of all, you DO have the snap rings on either side of the wheel bearing, right?

The three little bolts on the bottom control arm that hold the ball joint need to handle about 1.25 time the cornering and braking loads fed into that wheel.  If you consider the extreme, you could have 100% of the front end load on the outside wheel at a cornering acceleration of maybe 0.8g, and a loaded car weight of maybe 1500 lbs. on that end, or 1,200 lbs.  The little 7mm bolts EACH have more shear strength than that, and I am too lazy to calculate the clamping force to show that by friction alone, they will do the job.  You are now fully appreciating what light weight vehicles are all about:  if the car isn't some kind of bloat pig (i.e., like an A4), you don't need spare locomotive bits to hold the suspension together.
