Here's my experience with Jeep West:
Towards the end of last year I was looking for a shop to do gears, sleeves and gussets on my Dana 30 for my 2007 Jeep JKU. I came across their ad on Craigslist and decided to do a little research. My search turned up that they were a "sponsored/recommended" shop for the SW Washington & NW Oregon Wrangler Forum Group. To me, that was a good sign and I decided to email Jeep West to get some quotes. We exchanged a few emails back-n-forth about what I was looking to have done, particularly what was involved in having my sleeves and gussets reinforced, as I didn't want to go to another shop to have them done, and basically pay for the same labor twice. I got my quotes back and they were one of the shops in the Portland area that were more affordable for gears; so I decided to go with them. I booked an appointment, and they told me it would be about a day to get everything done.
So, the day of my appointment came, I coordinated with my dad (who lives in Vancouver) to be able to drop my Jeep off and get a ride to work that day. We dropped the Jeep, and I left my keys with them. Jeep West was in contact with me throughout the day letting me know the status of my Jeep. They got done with the Jeep probably around 5:30pm that night, and told me they would be around for a half-n-hour more if I wanted to pick it up that night. Unfortunately, I didn't have a right out there at that time, so I told them I would pick it up the next day.
The next day I went out there and picked it up. They told me they took it for a couple spins to break in the gears, and everything checked out great. So, I got my keys and headed out to the Jeep. The Jeep drove great back to my house, not an issue.
The day after, I had to drive to work. I hoped in the Jeep and off I went to work. On my drive I have to go over the Ross Island Bridge, as we all know there are a couple of bumpy parts there, I have never had an issue with them. So, I drove over them like normal, except this time the Jeep didn't like them. It started to violently shake, and keep shaking. It was the dreaded death wobble. I had to pull over to the next safest place and stop the Jeep. Work was only a few blocks away so I figured I could make it there just fine. I got to work and (called or emailed, I can't remember which one) and told them about my issue. They told me they torqued everything back to spec, but I could come back out and they would check it out for me. Well, I didn't have time during the day any day that week so i figured I would check it out for myself.
That night I got home, and loosened the typical components apart on the Jeep that cause DW and re-torqued everything. When for another spin, and got DW again. So, phase II of troubleshooting started; I took my track bar off and checked it out, both of the bushings were shot. I called up the manufacturer of the track bar and ordered new bushings for it. (Mind you this track bar was less than a year old). It took about a week for the bushings to come in and get the track bar re-installed.
Fast forward to the next week. My wife and I were heading to Long Beach, WA for a late 1-year anniversary weekend. With the Death Wobble behind us we were confidant on taking the Jeep there. We made it there in one piece! Heading back to Portland on late Sunday my wife was driving the Jeep. Going over the Astoria bridge she said my "brakes felt squishy" I told her she was crazy and didn't believe her. Once we got off the bridge, my brake light came on. We made it to the Safeway parking lot and I jumped out of the Jeep to take it a look. Front brakes looked good, made it to the back, passenger side check! Driver side, uh-oh! Both of the bolts holding my caliper were missing!
Now mind you this last summer, I replaced brake pads and rotors. I took those same bolts off to do my rotors. But when I put them back on, I sealed them up with some blue locktite and double checked them about 100 miles later, and they were torqued to spec. My only assumption is that when they were doing my rear gears, either the bolts were not torque to spec or maybe not even installed. Needless to say, my wife was pissed and scared to drive home on 3 brakes. I called my dad, and he drove his truck and trailer all the way from Vancouver to Astoria and towed us home. Over the next couple of days I had to go around to the Jeep dealerships and find a new caliper and all of the other parts I lost. The Jeep is all put back together and works fine now!
I never called Jeep West about the brakes. Between the track bar and the brakes there were too many things that made me scratch my head. I decided I was going to do it myself to make sure it was done right.
So, that's my story. You can form your own opinion from it. I know I have read some posts on this forum of some guys who have had successful interactions with Jeep West. I have a buddy and recommended Jeep West to him for his gear job as well. He went there and had issues with the gear install. He's on this forum, maybe he will chime in as well.
If you have any other questions feel free to drop me a PM.
