Yes...it IS nice to be able to go and tell a service manager, what needs to be done.
It reminds me of when I bought my FIRST new truck. a 1978 Ford 150 shortbox 4x4. I was new to 4x4's but I could sense something wasn't right with the four wheel drive, the backend seemed to wanna pass the front end.
So in reading some of the many magazines purchased, I discovered you can determine your axle ratio by jacking one wheel and turning the tire by hand and counting the revolutions it takes to make the driveshaft turn one rev. (then divide by two)
I found that my front was about 3:50 and the rear was 3:00...even though the tag said it was a 3:50.
So I head to the local dealer, talk to the service manager and he said the only way they would determine what the axle ratio was, was to pull the rearend and count teeth. If I was wrong I'd have to pay, otherwise it was warranty.
That pissed me off, I was a young grad out of school but still broke enough to not want to gamble. So I called the dealer I bought it from who were 5 hours one way away, described the problem, and was told get it in right away....
So I did, and drove in the service bay and the first thing they did was jack up one wheel, and turn the tire and counted...........and yes I was right.
And I was vindicated. And I DID call the first dealer and let them know. I even told them that a much larger shop determined it the same was as I did..and then I
and never bought anything there again.
