CHF & front end alignment

It does not affect the alignment.

I would not trust the work of any chassis mechanic who did not understand that.

Most of the weight is on the rear, thus most of the benefit.

Moved to Class A forum from DIY.

Picking up a new 30' Class on the F53 chassis. Read much about the CHF and the dealer is willing to do that but is concerned the adjustment will affect the front end alignment. For those who have done this, did you need front end alignment? Also, does the major advantage come from doing just the front end or doing it on the rear also provide benefits? Thanks for your replies. I need to hav this information by Monday morning.

as already posted does not effect alinement and do both of them

Dealer mechanic should go back to mechanic school and learn something about his trade!

Having CHF (Congestive Heart Failure) I didn't know all I need was a front end alignment to get well!

where in the OP post does he say a mechanic said so? all he says is the ""dealer"" is concerned

Have them do the CHF on both front and rear.

It will not effect alignment,,, BUT!!!!!,,,, that's not saying the current alignment is within specs.

The only adjustment on that axle is toe. Changing the position of the sway bar will not change toe. Camber is not adjustable on a straight truck axle unless you bend the axle itself which is not recommend by the manufacturers . (Some places do bent them anyway)
The major wear factor on these front ends is toe adjustment and rear axle alignment is part of it if done by a good truck shop.:B

Caster is also adjustable on solid front axles-- with shims that every truck suspension shop has. Been there, done that.

BUT, caster is not affected by CHF either.

Vandave, You're off to a great start by having the dealership do the CHF. One other suggestion would be to ask them to ensure the sway bar clamps are tight as well.
Oh, and getting a front end alignment would be on my "to do" list regardless of the work the dealer is doing.(Yep, the CHF doesn't impact alighnment) It's just my personal feeling but, I like to dial in as much positive caster as is reasonable and ensure the toe is in spec.
Enjoy,
