I recently bought a 93 Runner automatic with the 3vze. pretty well equipped and the body/interior is really clean and straight. it had some complications at first like the overdrive wasn't operating and the driveshaft was vibrating when going faster than 45. I replaced the thermostat and now the overdrive works great - it wasn't reaching full temp so it wouldn't shift. I just replaced the spider bearing in the front u-joint on my driveshaft and now it doesn't vibrate. It runs solid!

BUT...

Two more problems popped up out of nowhere: 1) the front wheels don't operate in 4wd and the light doesn't go on now. 2) there is a gurgling coming from the engine on accelleration and when I turn the engine off. sounds like a cooling issue?

Any input would be greatly appreciated.

Thanks!!

 

Hi welcome to the board.
Sounds like you are mechanically inclined.
The 4wd problem - this might due to vacuum leak so that the front axel doesn't engage. Do a search for it 4wd problem ADD or test that all you hoses are attached properly

this might also cure some of your gurgling noises (unless it is a cooling system issue)

 

right on. I'm going to check it out when I get home from work tonight. I just moved from Oregon and I don't have any tools down here so I'm kind of "garage-hopping" trying to troubleshoot this thing. Thanks for your help! this forum ROCKS!!
