Not in Pasadena but close by... I use Scotty's Brake and Muffler for any repairs that I do not want to do and have had good workmanship from them. Bob, the owner, races in the JeepSpeed series, and several of the workers have jeeps and related trail gear.. Give them a shot..

They are almost in Temple City, where I live, a few blocks from home. I mostly have them smog, brake replacements for my Wife's Jeep, as i do not want to be responsible for her brakes.... Cam belt replacement in my Honda, A/C work, that kind of stuff.. They will work on about anything that needs fixing...
And I'm in the same repair cycle on my wife's Liberty.. 155k miles and it is starting to show signs of repairs needed.. new struts, bushings, fix a small oil leak, stuff like that... So maybe a time to start with a lift, bigger tires, locker in the rear.. maybe even a 4x4 conversion as it is a street cruser... She told me that I can not make any changes to it....
