'89 4X4 Remote Free-wheel problem

RINEYVILLE · 03-13-2007, 02:18 AM

Has anyone else got problems with the front hubs engaging randomly? I have been told it may be a leaky vacuum line to the front hub actuator (?)
I'll try to figure out where that is and see if I can fix it. I have the vacuum line diagram but haven't figured out which one goes to the front hub actuator.

Start at the hub actuator and work you way backwards. while it is running, you should hear a whitsle if the hose is cracked anywhere. My buddy had 91 mazda with a similar problem. He used a sponge with soapy water to find the leak. Turns out that was the problem..... hope you find it. Good luck.

It'll be a couple of months before I get back to my truck. I'll use that technique and let you know how I fared. Thanks again.
