Yeah the wrangler he has is in great shape all around others that he had a shackle welded where it attached to the front axle.
Not sure which one, maybe UCA but he says when you're going down the road about 45-50 mph and hit a crown or an uneven spot it throws the vehicle sideways and it feels like it's gonna flip over.
It's not death wobble but something is off.
I told him it could be the lift components were wrong for that build and maybe should have used specialty parts in addition to the lift such as a drop Pittman arm..etc.
He insists the lift was done professionally.....I just need to go look at it but it's in Pennsylvania.
Sounds like bump steer, coupled with poor suspension geometry.
VERY few "professionals" do a lift properly. A well done lift on a wrangler is very expensive.
