After 60,000 miles, the front outer half-shaft boots tend to tear and leak grease. In most cases, only the boot will have to be replaced; however, if it is not repaired soon enough, the half-shaft may need to be replaced. The front outer boots are put under heavy stress because of their involvement with the suspension when making turns.Google+

It's less expensive to replace the entire 1/2 shaft which includes a new CV boot. At 60,000 my front left went bad and now at 70,000 my right front is leaking. Total cost to repair one side is around $300.00 & the repair can be done at a Firestone complete auto care shop. I refuse to pay BMW labor costs..ridiculous!

Torn boot just before 60k. Replaced boot but apparently not soon enough because at 70k started getting the clicking and tires skipping at slow speed.

Dealer said CV boots were cracked & leaking. Cost about $1400 P&L to replace two CV boots.

Replaced both inner and outer on Driver and Passenger sides for $850
Now I will be replacing the passenger side outer again at 67,000
Inferior material or design this is not right.
