need help with 1985 auto lock hubs. . .
I'm new to the forum and new to Toyota trucks. I recently bought an 85 sr5 truck, with about 180,000 miles. Yesterday I was greasing the u-joints, and was turning the front driveshaft by hand. After a rotation or so, the fron hubs locked up. I didn't try to unlock them until this morning, and they felt like they were haveing trouble unlocking. Then when i started to drive there were clicking noises coming out of the front hubs, about one click per rotation. I have used the 4wd a few times, and they have not given me any trouble. Any ideas on what is going on now? I don't have a service manual for this truck yet, but I certainly plan on getting one. Thanks in advance for any help!
