Hi Katrina.
Where are you located is it near a city Center?
You would be wise to seek out an RV suspension and running gear shop like McCallister Spring. I believe they are still in Vancouver.
In Calgary we have Standens Spring and
Axle.
Sometimes with running gear, when this happens it is a wake up call of sorts to replace assemblies such as the
axle to a new, heavier grade part.
If the
axle has cambered with relatively normal use it may be fatigued and not easily corrected - At least for the long run.
Do a search of RV Service Shops and Dealers and ask around who is the best for suspension and running gear.
See if you can post a pic or two?
