4.4 4.8 Timing Chain Guide

[StephenVA]

Thanks for the insight as it coresponds to what I call "Good Practices" of vehicle maintenance. Replace and repair as required before total failure occures. Always cheaper than the alternative results. (ask me how I know...did wheel bearings once on another vehicle, after I egnored the squeeks, creaks, and noise. Welded bearing races on the spindles, trashed the rotors due to heat warping, had to replace the spindle, brearings, rotors, brakes, ball joints, tie rod ends, etc. Out in a driveway while it was snowing. What fun that was. Lesson learned the hard way.)

Keep up the great posts as it help us all to do preventive repairs to avoid the death rattles.

I follow the preventive maintenance model for severe vehicle mileage. I change the oil (Mobil One) every 12-13 months or approx 3,000 miles. Lots of short distance trips (less than 6 - 50 miles), followed by a run around the interstate with a heavy foot. All the fliuds are getting replaced this winter (49K) as I have another vehicle or two to use when weather sucks or have a meeting where safe parking will be an issue.
The X5 sits outside with a Battery tender on her and lots of Wax. One very clean 4x4 beast.
