Changing the FD oil today and have found the first evidence of metal shavings on the magnetic plug. I change the FD oil very 6k with a Mobil 1 75-140 and it looked good as new when it drained today as it has on the past. 05 LT with almost 45k. Purchased used 3.5 years ago and have put just over 15k on it. Primarily used for daily commuting with a round trip of 30 miles. Spring and fall she will take me to NC and GA to officiate tournaments so it will see anywhere from 200-400 miles on some weekends. So, ballpark figure how long before having a total failure? What does a failure look like? Back wheel lock up? Grinding? Anything I can do to limp it along and stretch out a total failure? And of course, what kind of $pend am I in for? Look forward to the feedback.
