I used to take my Jeep XJ to Off Road Warehouse on Balboa, you may want to check out a Firestone service center, you pay roughly 100 or so for the alignment but it's a lifetime alignment, good deal in my opinion.
If you ever need suspension work done, talk with the owner Eric. He's had this shop open for 14 years now and does really great work.
He gave me a nice discount and was done in about 2hrs. He was really cool, and even told me to come back in 500 miles for a re-check to make sure everything is tight and aligned again if needed.
