Yes and no.
Yes check the rear diff.
That said, in the middle of the driveshaft a carrier bearing as this has a two piece driveshaft. The carrier bearing is mounted in rubber. It is suspect.
As I stated earlier clunks from changing direction are likely the two arms holding the rear diff at the front near the pinion. Shown here is one and the coupler. Again; when does it make the noise? What conditions, throttle, gear, brakes..... ????
No noise from shifting. The noise starts when you start moving forward and increases in rapidity with speed. Decreases when slowing down. Touching, taping, pumping the brakes doesnt appear to alter the noise other than the noise slows down when the car slows down. It's still torn apart so I cant test the E bake effect but will inspect it when I can.
So when I originally jacked up the car and put it on stands the driver side rear wasnt turning at all. So I thought that was the issue. But after 2013s helpful comments and taking it apart and not seeing anything that really looked "off" I tried looking around, wiggling and shaking things looking for some play in something. Then Gville comments had me under the car again checking and wiggling the drive shaft. Then I thought to myself, How funny would it be if it was the other side and I took apart the driver side and not the passenger side. That would probably be typical for me. I grabbed the passenger side axle and wiggled it and turned it and pushed and pull and right when I thought. Nope nothing wrong there I heard 1 single "clunk". I tried and tired to get it to "clunk" again and almost gave up again. Then a single clunk again. What if I raise the passenger side tire up with a jack so it's more in the normal position and not hanging down. Viola!
Its more of round snap ring sitting in a grove in the axle.
Again, JM2C but the axle is clipped to the side gear. The side has movement. Pretty all of them are going to move. I don't think that is your noise. The other side moves too, yes?
No, the drivers side that I took out had to be pried out with a 3 foot 45 degree pry bar. There is a clip. Here is a picture from the driver side axle I already removed
Maybe the clip fell out and is in the bottom of the differential? Hopefully in the bottom. It's maybe ground up. I wasnt planning on taikng the differential apart just changing the oil but now maybe I will take the back off. Clean it out, and put it back together.
The inside half shaft joint is a trunnion. The axles slips in and out of the trunnion to allow for the the suspension motion.
All of that said, the trunnion joint has a lot of slip. Like it could likely move inward an inch. So the fact that it stops moving so quickly leads me to believe the clip is there and working.
If you pry from both sides equally, it doesn't take near as much force to pop the axle free. Doing one side only binds the clip.
Doing this without taking the outboard axle end free will show that the trunnion has more motion and that the clip takes force to dislodge.
Strap your phone under there and go for a drive. Maybe pinpoint where the sound is coming from. Haha!
