good morning my name is ***** ***** I will assist there are a couple of reasons for thisthe car has 3 driveshafts that have universal joints. one or more could be seized causing this issue.a bad transmission mount can cause this issue as well. clutches in the differential could also cause this issue Roy
Customer: replied 6 months ago.
Should I begin by changing the differential oil and add and additive (this seems to be easiest to begin) and, this car didn't get driven much in the last 25 years (only has 47,000 original miles). Also, would a bad universal joint be obvious; what are the signs and how do I check them?
Thanks
Phil
