No build thread for the 1988 4Runner so I'll just have to post updates as standalones like this until I get around to it.
The u joints were replaced by a NAPA place about 15 years ago and finally got enough slack in them I decided to fix them. Trail Gear sells this Matsuba kit which appears to be high quality and Japanese.
