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.

We are the original owners of this 2005 X5 3.0 and had the vehicle towed into our local Service Dept. (The tow was required due to an Engine Failsafe indicator popping up while the car shut down/stopped operating while in motion - Service says the issue that caused that problem is an Ignition Switch issue?) and were advised that the CV Boots on the front Transaxle are worn out and need to be replaced. In addition, the Service Dept. advised the Valve Cover Gasket is leaking and should be replaced too. Ouch, $2K in total repairs this time around, and yet, we have maintained this vehicle very well, we are the original owners so we also know how it has been driven (gently over the years), and it only has 85K miles. Again, ouch.

I had to pay $2613.75 to BMW Concord because they said that both my CV boots was torn. last July, at 109080 miles, I had to replace the Belt Tensioner, Pulley & Belt. Same place. I love my BMW but it's just too expensive to maintain.

radiator and thermostat died. High pressure built up caused coolant reservoir tank to cracked. Coolant flush away completely and suddenly. Persistent "check coolant level" sign, Replaced all for $1500. Now found that CV boot of front axle are torn and grease leak everywhere. Need to replace whole axle? Mechanic says it is not possible to replace only CV Boot. Cost $700 to repair. 2005 X5 4.4l @San Jose

Driver's side front inner and outer booties ripped but still held grease and no clunking. Replaced both and kept the original half-shaft.
I have had to replace both, my other problem has been the tail lights have a steady failure issue, I had to replace two tail lights on the Driver's rear and three tail lights on the passenger rear, the newest issue is the rear wiper stays running even when the stalk switch has been changed to a new one but STILL runs without the switch installed!!!!!!
