Hey yall, I am new to the site because i just picked up a wrecked 04 4runner with 31k miles for my wife (really 4 me) and rebuilt it... I am just about done with it and I believe it is an all time 4WD model (swich only has 4H and 4L). I have read multiple posts about having issues engaging 4L on this site. I have tried rolling in neutral, shifting in and out of neutral, going in reverse, and doing all of the above on asphalt and on dirt. The light just flashed and makes this annoying beeping noise. Is their any other advice you guys could give me about diagnosing this problem. I would think it would be from the wreck except for the fact that it did not get into the suspension, transfer case, or frame at all. this is my fourth Toyota but first 4runner so I am a little stumped. Any help would be very much appreciated.
