So after I had a Rough Country 4" long arm lift kit install (https://www.roughcountry.com/jeep-l...ind=2010-jeep-wrangler-jk--2-door--4wd-737419) my Jeep drifts hard to the right. The installer said it's due to the caster and can't get it out. The Jeep had been turned over, but according to the owner and police report, it was a slow rollover. The mechanic said he thinks that the front differential is twisted because of it. It drove true before the lift. Does this sound legit? I don't want to spend too much money on it... a new (rebuilt) differential is about $1,000.

A friend told me to get these and they would get the pull out https://www.cjponyparts.com/special...stment-jeep-wrangler-jk-2007-2018/p/SPC23540/

Thoughts?

Get an alignment and adjust the castor. You have adjustable control arms

Definitely take your Jeep to an alignment shop. Your caster is set by your already installed adjustable control arms. If the alignment shop cannot get you within spec, then you might have something tweeked. Post your alignment sheet when you get the alignment done.

This is what it's set at now. I have an appointment on Jan 10th with a different company. They did say that it's possible something is bent based off of this.

That is a large drive-to-passenger side difference. Likely the cause of the drifting. Possible it has damage but possible error on the shop as well. Looks like they didn't even attempt to adjust the Caster? Your kit comes with adjustable upper and lower CAs, no excuses the casters shouldn't be right, or at minimum evened out.
I would say another shop might be in order as well. One willing to show you why it can't be aligned properly, not just say it and hope you walk away.

Thanks! I’m trying to stay positive… I’d much rather spend money on useless body armor instead of a new differential 🤣

Yeah..... Whoever did that "alignment", should be fired. They literally did nothing to your caster or thrust. I mean 💩, you could of done a better job with a tape measure, a jack and a few wrenches in your driveway! Hopefully this other shop knows what they're doing.
