Looking at a 99 SR5 with 178k. Its a 4wd model but no e-locker. I know book. I think its a fair deal at $3900. New rims and tires and roof basket is a plus. There are some 4runners down here as far as a e-locker retrofit. From everyone's experience here just wondering where are the trouble areas I need to look for. He says the transmission leaks about a quart of fluid every two months. Hoping its a pan gasket. Is there something that leaks that is common that causes this? Must trying to get opinions to make sure I'm not getting screwed.
