Hey guys, new issue! I have a 1994 f150 4x4 auto with the 302 v8, I've been hearing a strange clicking sound at low to low-middle throttle ranges, around 15-30mph, so mostly 1st and second gear. It sounds like its under the truck, my guess is the transfer case, driveshaft, or rear differential... Somewhere in that region. If I swerve or give it a little more gas, I can't hear it anymore. It doesn't shift rough and the 4x4 still works. Please tell me is a U-joint on the transfer case or something cheap and easy....... I'd love any help that y'all can give me! Thanks!

Clicking sounds more like a U-joint. Look for red rust dust around the u-joints, that's a indication they are worn out.

I'll have to check that out tomorrow when I get back from work, thanks! Would the whole driveshaft need replacing? Or do the u joints come off the driveshaft? I've only done the u joints on the front when I did the ball joints

I cant tell you for sure but my friend had a clicking underneath his truck and it ended up being the pinion gear. Hope this helps.

Same procedure, you need to remove the drive shaft in order to get to the u joints, you will need a 12 point 12mm wrench and some elbow grease to get the rear bolts out from the axle to slide out the drive shaft. Also if you have a center support bearing you will have to un bolt that as well. I'd use a ball joint press to get the u joints in and out vs sockets and hammering them in cause its likely to bed the ears.

Here's an issue, u joints seem fine! Clicking got worse today..... Any other ideas?

I had the same deal it clicked really bad when accelerating. Upon inspection the u joints looked fine but when we dropped the driveshaft the back one was so stiff and we replaced it and it solved the problem. Hope this helps!!

I hope it's something easy!

Possibly wheel bearings or u-joints in the front TTB?

I just got under the truck and watched the u joints and transfer case as I pushed it forward and back, the u joints don't look like they have any slack in them, most f the slack is coming from the transfer case. I noticed it kinda slams into drive a little worse than is used to. Now on the farm I had to have her in an out of 4x4 more than I usually do, to pull a hay wagon in a little mud, But that was was a week ago! This started sunday on my way back from church!
