Alignment question

Not long ago we had our 2014 Tiffin 33AA RED aligned. The front end was aligned without any problems but we were told the rear was out of alignment and because it was "fixed" it could not be aligned. The rear axle measurements are as follows: Drivers side: Camber -0.2; Toe -0.23, Passenger side: Camber -0.4; Toe 0.10, Total Toe -0.13 and Thrust Angle -0.17. Thrust Angle was highlighted in red.

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.

Thanks,
Robert

You didn't say if you were having any driving or tire wear issues... I wouldn't mess with it. They might screw it up worse.

Robert, if your camber, total toe, and thrust angle are significantly out from oem specs you should notice excessive tire wear or pull. On the other hand, there is some degree of tolerance and just because one of your angles are not within oem specs does not mean it wont drive straight.

Finding a HD shop to do good alignment is another issue. Dont assume that because its freightliner (or any other manufacturer) they will do the best alignment. It all boils down to the tech's knowledge and their willingness to do the alignment correctly. I suggest you find out from others who have good reviews on a place. I have heard good things about most Southern Tire Marts. Sometimes small independant HD shops have the experienced techs.

I will try and make some calls for you in the morning to some HD contacts i have to see who they recommend.

I'm afraid I can't answer most of your questions, but being a 2014 model I would pursue getting it aligned now. When I had my 2014 aligned Freightliner paid for it since it was so new. Turns out my rear axle was okay. I used the Dallas Freightliner off i-20.

Have someone follow you down a straight road. Does the front and rear track each other or does the coach go down the road sideways?

If it goes sideways, get it 4 wheel aligned which will probably require breaking the welds.

I had my Ford chassis aligned by Wingfoot (Goodyear truck service) because my operator's manual said to have a new coach aligned after loading.

It drove great for a gas rig but the alignment made it difficult to drive. I took it back and they had someone else check it out. They made new adjustments to their original alignment.

I believe that the first alignment was done by someone with low experience and the second time it was done by their alignment expert.

On the short drive home it felt like it was handling better than ever.

Safe travels. JD

Kaiser Brake and Alignment in Eugene, OR will do a rear alignment that needs cutting and welding. They did this when doing the rear of our Beaver Marquis.

Be sure to remind whoever does your welding to disconnect the battery negative terminals before welding. Otherwise you run the risk of frying the engine and transmission computers.

The Petro Truck Stop is probably closest, but they may not break the welds. He sent me a list of other shops in your area.

AMA009,
Thanks! Cowsers did the alignment and said the rear was out of alignment. Don't think they will break a weld but from the response I've gotten don't think it really needs aligning. So, will probably go back to Cowsers for the front end alignment when needed.
Thanks again.
Robert
