I'm at my wit's end here with my 1995 F53 motorhome alignment issues. Just got back from the alignment shop and they're telling me the thrust angle is way off but there's absolutely nothing that can be done about it on the rear axle. They basically shrugged and said "that's just how it is" and sent me on my way.
I'm having a hard time accepting this answer because the RV pulls to one side constantly and I'm going through tires like crazy. Before I give up completely, I need to know - can thrust angle actually be adjusted on Ford F53 chassis? I've heard there might be ways to reposition things in the rear, but I need specifics on what methods exist and whether this is something that can realistically be fixed.
Thrust angle on Ford F53 motorhomes can often be adjusted through rear axle shims, leaf spring adjustments, or axle repositioning. While shops may claim nothing can be done, several adjustment methods exist for correcting rear alignment issues.

Here's what you're dealing with. Your shop is partially correct - thrust angle adjustment on F53 chassis is extremely limited due to its solid rear axle design. While minor adjustments may be possible through shims or specialized hardware, meaningful thrust angle correction typically requires axle housing repositioning or replacement, which is beyond typical adjustment procedures. The key is finding a shop experienced with heavy-duty RV chassis work.
