ohdaho Posted January 20, 2011 Report Share Posted January 20, 2011 (edited) 97 4runner wont engage 4 wheel drive today. What a shitty day for it to happen.Light turns on, but the rear left wheel is not spinning. Its just being dragged along. Then I put it back into Hi2 (from Hi4) and still noticed the rear left wheel not spinning.Any ideas?

jporter12 Posted January 20, 2011 Report Share Posted January 20, 2011 Engaging 4-wheel drive won't change the way your rear differential works. Your rear is most likely a limited-slip. The transfer case just engages the front end. Either nothing is wrong with your truck or something is terribly wrong with your truck. Really Pauly? I would've expected something less retarded sounding from you. Unless you meant to say that his rear differential is NOT limited slip. Limited slip, sometimes referred to as positraction (which is a GM trademark for their limited slip differential option) will deliver power to both rear wheels, and let them slip enough to make turning possible without damaging anything.Anyway, if the fronts aren't working, there's probably a transfer case, of front axle engagement problem. I haven't worked on any Toyota four wheel drives for quite a while, so I'd have to look into it more.Is there a lockout hub on each front wheel, or are they automatic (or maybe constantly engaged?)Does the 4wd light flash or anything, when trying to put it in 4wd?

jporter12 Posted January 20, 2011 Report Share Posted January 20, 2011 It looks like the front axle is constantly engaged, so it's most likely a problem with the transfer case, or transfer case actuator motor. Quote Link to comment Share on other sites More sharing options...

jblosser Posted January 20, 2011 Report Share Posted January 20, 2011 Never understood why anyone offers a 4WD with an open rear diff...I've posted this before, but it bears repeating:How to tell if your truck has limited slip:- Find a dry parking lot- Put left foot on brake, mash pedal to the floor- Put right foot on the gas, mash pedal to the floor- Lift left foot completely off the brake, leaving gas to the floor- After 5 seconds, stop, get out of truck, and walk to the back.- If you see one stripe, you have an open differential- If you see two stripes, you have a limited-slip differential- If you see three stripes, put down the beer and give your keys to someone who's not drunk- If you don't see any stripes, check truck for Ford badge. 2 Quote Link to comment Share on other sites More sharing options...

ohdaho Posted January 22, 2011 Author Report Share Posted January 22, 2011 I think its a frozen caliper. Maybe water in the brakeline, or some somethings leaking and freezing over. Cars fine after driving around/warming up.this is a recently acquired used vehicle so i havent had the chance to change all fluids. Quote Link to comment Share on other sites More sharing options...
ohdaho Posted January 22, 2011 Author Report Share Posted January 22, 2011 When there was a lot of snow of the ground, wheel didnt spin/move...e.g. dragged along. Same characteristics whether it was under power or not. Quote Link to comment Share on other sites More sharing options...
ReconRat Posted January 22, 2011 Report Share Posted January 22, 2011 (edited) I agree, maybe the darn brake is dragging or locked up on that wheel.The brake caliper piston could be seized or stuck...Even if it's a drum brake, there are ways to malfunction and do that.edit: oh and hey, check out the stupid parking brake. Sometimes the ones that use a cable get rusted up and won't let go. That makes the brake stay engaged a little or a lot. Usually yanking hard on the cable with vice grips toward the wheel, will free it up until the next time the parking brake is used.

ohdaho Posted January 22, 2011 Author Report Share Posted January 22, 2011 Yea thats what the guys on the 4runner forums said.Apparently 3rd gen 4runners can have a parking brake issue. Nothing too cosmic, but a lot less expensive than fixing the diff or t-case. Quote Link to comment Share on other sites More sharing options...
