After alignment the front axle measurements are as follows: Drivers side: Camber -0.3; Caster 3.7; Toe 0.02, Passenger side: Camber -0.1; Caster 4.2; Toe 0.03, Total Toe 0.05 and Steer Ahead 0.00.
I spoke with Gary Harris at Tiffin who said it is not that unusual for the rear axle to be out of alignment and was not that difficult to correct but a weld would have to be broken to align the rear axle.
Our question is: Based on the current rear axle measurements, is the rear axle out of alignment enough to justify having the weld broken, aligned and re-welded? From the printout I got from the alignment shop (truck & motorhome shop) only the rear axle Thrust Angle was highlighted in red, I guess indicating it was out of an acceptable range. My past dealings with the Ft. Worth, TX Freighliner shop has not left me feeling comfortable in their ability to perform this task. The shop which did the alignment said they would not attempt to align the rear axle.
Your thoughts and advice will be appreciated.
My question would be: Considering that a weld has to be broken and re-welded in order to realign the rear axle, doesn't it mean that it wasn't properly aligned when it came from the factory? Or, if simply driving your MH over normal road conditions can cause the steel to twist, why aren't they using stronger steel in the first place - to stop this problem from occurring? Cheers.
