Ok so backstory that I believe to be related, two days before incident I hit a huge semi tire on the freeway. Fast forward to incident. I'm making a 3 point turn, go into reverse, no problem, go back into first gear and car won't budge, feels like there is a wheel chock holding it back, so I give it some more gas and hear metal grinding so I back off. Put it in reverse, same issue. So I put it in neutral and push it, same thing!

Turned the car off and got my jack, lift up drivers side do a quick inspection for anything obvious, pitch black out I see nothing. I drop the car and now it moves! No grinding at all! I parked it and drove it the next morning and now there is a thumping noise that increases with speed. Parked the car and haven't had time to look at it yet. Looking for ideas of what could be the issue. I'm leaning towards cv axle/wheel bearing. What do you guys think?

I wouldn't keep driving it until you figure out whats wrong. I would start by getting all 4 tires off the ground and trying to rotate them by hand. Look for any binding, noise, anything really. I would then dump the fluids from all the drivetrain parts and see what that looks like too.I would start at the transfer case, then rear diff, then transmission.

My very first thought was tcase, but would it grind in neutral? Also I'm not driving it, it's been parked

Biggiesacks

yah if the wheels are spinning so is the drivetrain.

Ah true, my wishful thinking clouded my judgment.
Any ideas why jacking up the driver wheel would rid the grinding?

Super speculating here, but maybe some metal was stuck in the gears and just through moving the car around and what not it made its way out of the gear set.

Could make sense.
Think the cv axle popping out is on the table?

Biggiesacks

That would be easy to diagnose by doing the first test i recommended.

Yup, been planning to do it just waiting for my day off

You ran over something and two days later the car acted up? I'm not going to say impossible but ....

You were shifting gears when this happened. I wonder if you managed to get two gears selected at the same time. That would do what you describe and then could magically disappear.

Wasn't shifting at the time, was in 5th in the freeway, and why would I have the thumping now :/

barneyb

Have you checked for bent wheels?

And yes you were shifting at the time, you were doing a three-point turn. What I was suggesting was that the lockup might not be related to the incident on the highway but instead was a hiccup in the transmission.

Oh sorry my mistake, thought you were asking if I was shifting when I hit the tire.
Now I understand, I wish it was something as simple as that, but why the sudden thumping now

barneyb

What I suggested is only a guess - one possible senario of many.

Could not replicate noise by hand, had to put the car in gear while it was in the air. Noise is coming from the center according to my buddy.
