I installed a 2.5 inch susp lift and a 1.5 inch body lift and put 37s on. Drove around with this setup for weeks with no issues. I went offroading once, and now i have slight wheel wobble at 40-50mph. I thought it was just mud caked in the rims. So i cleaned it all off, however it didnt fully help. Alignment? Tire out of balance?

 

I'd start with having the tires balanced. Might have lost a wheel weight or bent a wheel.

 

Ball joints?

 

Check your tire pressure and lug nuts.

Lift a front wheel and give it a good shake in all directions. If it wobbles you may have unit bearing or ball joint issues.

 

I had that problem just needed to get the wheels balanced fixed it

 

Is it a speed dependent shimmy that happens every time you reach a certain speed, or is it random and not easily repeatable?

 

knock on wood but i think its fixed. Drove fine this morning, i had tons of mud caked on still. So that was probably throwing everything off. But it was only at 40-50ish mph.
