Here are a few that I could recommend:
Auburn Off-road & Car Repair: (253) 939-5019 – They know their Jeeps! One of their bolt turners is a member on here (CC).
Cobweb Specialties (Edgewood): (253) 841-7301 – They usually work on high-end stuff, but can do anything.
OR
You can try a specialty shop. I’ve seen an auto electric shop on Pine Street in Tacoma, but never have heard anything about them…
