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.

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.

I had to replace left and we are watching the right. Said it could also happen from something hitting it on the road.

Replaced inne-boots about a year ago. Now both outer boots are leaking. $1100 quote from dealer
lost both front outer boots probably within 1 years time and expect it again when I get to double and triple the mileage because neoprene wasn't used. Not extremely difficult to change as the axle is splined but non the less not many issues like this happen to Japanese cars.

Got an estimate of $980.00 from dealer
Yeah both front CV boots were torn had to replace the axle and bushings. Very costly. You would think being built for German winters these cars could handle a New England winter but I guess not

Just bought the car expecting repairs. Same issue. Considering ordering CV replacements myself from eBay and having a shop install.
Sewickley BMW idenitifed small leaks during annual inspection. He estimated $1,200 to repair. NOTE: This estimate DID NOT include new CV joints; only the CV boots. Dealer claims issue is NOT ccovered under warranty. PURE BS. Maybe they will cover the repair AFTER the CV joints are ruined!!!
