New noise

[CMGRover]

Just this morning the LR3 started making an odd noise. It's drivetrain related. Whenever you accelerate, it makes a popping/racheting noise. Turning doesn't effect it, and the driveability is normal. Can't feel any vibrations. I checked the front CV joints real quick and I didn't see any rips/tears in them, so they didn't dry out.

Any thoughts?

Sounds scary. I'd just go to the dealer, but that's just me.

Nearest dealer is 2+ hours away, but there's a shop here that specializes in Euro vehicles so I'm going to try to get it in there by Monday.

I was wondering if maybe something got lodged in a tire...like a huge bolt. But the acceleration throws me off.

Yeah it's sort of strange that it's only when you accelerate.

Took it in today...CV on the driveshaft is bad. Ordered a new one from Atlantic British, it has greaseable joints, which is a plus to me.

I know a driveshaft is pretty easy to do DIY, but the guy at the shop is super nice, lets me bring in parts and diagnosed it for free so I'll pay him to do it. Getting to know him pretty well.

do you have to replace the entire shaft or just the CV Joint?

 

[CMGRover]

Whole shaft, the CV joint can't be found. I guess one could get creative and ghetto rig it with a U joint, but since it's a DD, it's easier just to get the whole shaft anyway.

How many miles do you have on your rig?

 

[CMGRover]

Just about 87k.

I had to have both of my differentials replaced. Fortunately all under warranty. The front was replaced at about 32k or so and the rear about another 3-5k after that. Both had bits of metal and I felt slight vibrations at speed. My dealership replaced them immediately without question. But this didn't affect my acceleration.
If you're hearing a grinding noise and loss of power on acceleration that sounds like something not connected with the differentials. Look to your transmission I think. Just a thought.
