Front end align on a fairly new coach

Fun Trivia Fact:
They do not align them at the factory before shipping.

I have about 3000 miles on this coach I think I will carefully watch the tire wear and maybe do an allignment if the wear starts to show that it is warranted.

We also have an F53. The steering wheel was always cocked to the right about 30 degrees when going down the road, but no pulling. Long story short, one of the front tires began to cup on the outside so I brought the rig to a local reputable truck alignment shop.

To correct the alignment, the tech told me he would have to "bend" the front axle. I did a good bit of research and it seems the only way to adjust Camber is to bend and shim the front axle. Most folks who posted the same did not experience any problems doing this so I gave the go ahead.

Wow, what a difference in handling post alignment. Also, the steering wheel is now true when driving strait.

Money well spent.

Hendersons and Brazels are both well known experts when it comes to RV chassis alignment. Read what they have to say: Wheel alignment

Straight axles do not change much with load but they do change and they may also not be set correct from the factory.

The camber and toe-in DO NOT change with chassis loading on an "I" beam front end. That's an internet fable. The caster can change slightly with loading. Manufactures representatives and dealers do sometimes advocate this fable, but they are clueless.

After reading many posts it seems that the general feeling among class A owners is that the the alignment ( from the OEM ) is not correct for a MH I don't spending the $$ to do an alignment but I wonder if I am reading these posts correctly. The changes I have made to this point have calmed this coach down I initally had some handling problem when it was windy. I did not have problems from passing trucks etc... Just wondering.

So on a calm windless day it runs fine? Also with passing trucks? Doesn't sound like it has an alignment problem. RV's are big sails, basically.

If there are any signs of tire wear or poor handling the first thing I would do is have the wheels aligned. While most body builders claim they align the front end after the unit is complete they do a marginal job at best.

Given the average cost of a tire is about $500.00 it's far cheaper to spend $120.00 on an alignment than $1,000. on a pair of tires.

As a side note Ford does not cover tire damage done by an out of alignment condition. Back in 1999 they put out a technical service bulletin announcing the change. It seems too many body builders were doing a poor job of aligning the front end after the body was installed. They were passing the problems off to the chassis manufacturer.

My 2004 Monaco came with a coupon for a free front end alignment to be used after the coach was loaded.

I didn't think it was necessary. Two years later I wished I had done the alignment, those two new front tires were expensive.

I suggest getting an alignment.

My 2017 Thor Hurricane 35M actually had a sticker in the driver's compartment. Here's what it said:

NOTICE
The front suspension and steering system of this motorhome was factory aligned prior to it being dispatched to the dealership. The alignment is,however, greatly affected by the way the unit is loaded prior to travel. This loading includes how much cargo, water, and LP are carried as well as the distribution of said cargo. Thor Motor Coach advises to have the alignment checked in the fully loaded condition (the way you would normally load the unit to travel). Not having the alignment checked and reset may result in abnormal tire wear.

I paid to have the coach aligned after it was fully loaded and no adjustments were needed.

One thing that cannot be done at the factory is to align your coach when fully loaded for a trip. The alignment of an RV does change when the coach is fully loaded.
If it seems to handle OK and if you can rub your hand across the tire tread and not feel any scuffing, than you might be OK. Just keep an eye on tire wear.
