Ranger shuddering when turning in reverse

So try it in 4wd too.

Limited slip rear diff? Try changing the fluid + additive (if it uses it). ABS? See if a wheel speed sensor is loose/broken/missing. Check the "spider" gears inside the diff for damage.

Check for tierod / balljoint / wheel bearing looseness with the wheel turned to the side. On the ground and jacked up.

Does this occur when you let out the clutch to get moving or does it star t to happen if you are already moving and you turn the wheel?

Yes, and will do.

No. At least, no ABS lights, and it certainly skids, and has as long as I've owned it.

Again, will do. Could this cause issues in reverse and turning in one direction only?

Again, will do. Tierods & control arm were all good 10K & 1 year ago, but that could have changed, especially with the off-roading abuse. Both front wheel bearings have been changed last year.

Thanks for the help on where to start, I really appreciate it.

When the vehicle is already moving, clutch fully engaged. Not sure if it happens with the clutch partially disengaged, something else for me to check.

Engine mount? Remember the engine/transmission is twisted the opposite to "normal" direction when backing up, tending to lift the passenger's side of the engine rather than the driver's side. Raise the hood and while holding the brake, carefully "slip" the clutch in reverse while watching the engine, then repeat in a forward gear. If it moves a lot more in reverse, you've probably got a broken passenger-side motor mount.

This makes a _lot_ of sense. I wouldn't be the least bit surprised to find you hit the nail on the head with this one. I had a golf back in the day with a bad motor mount, and I seem to recall it being a lot worse in reverse. The engine shifting on the bad mount could cause the drivetrain to get pushed slightly out of alignment as well, explaining the "coming from the rear" feeling. this will be one of the first things I cehck. The parking brake isn't awesome in this thing, so I'll probably chalk the rear wheels as I perform this check. Thanks for the idea!

But I guess you would still have to explain why it only happens when turning, and only when turning in one direction.

Something else to check out - thanks!

I'd take a close look at the front CV joints.
