Umm first the 89 has leaf springs in the back while the 90 to 95 have coils. So the lift wont work on your runner. Secound I can work on the truck or figure out what your problem is and fix it. I have worked on toyotas for a while, plus i do competition rock crawling with my truck so i kind of know my toyota 4x4s. Let me know and just swing by and ill take a look at it.
