popping and grinding on take off

I'm having a lot of popping and grinding when accelerating. I began investigating and noticed this. I'm a rookie when it comes to mechanical so I'm depending on you guys. Also as a side note I removed the 1 1/2" body pucks recently and I still have a 4" suspension lift with rancho 9000 shocks. What exactly is this and what suggestions do y'all have to fix it.

That flat piece of metal is linkage drop bracket that came with your body lift. It should have come out with the pucks.

So does the black prong go into the hole the bolt directly above it is in, and would that explain my popping sounds?

There should be a bushing in the folded piece of steel attached to the transmission hump, but it might have been removed when the adapter was installed. I forget exactly what it looks like, but the black rod in your picture goes in there normally. Not the best setup, but that the way they built it.
It probably twisting your linkage. That might be the source of your noise.

I personally would chunk the whole stock linkage assembly and get a Novak Cable Shifter. Especially since you said you had a body lift + suspension lift. I had a knocking noise under my jeep but I eliminated it with the Novak cable shifter, plus it engages into 4wd a lot easier.


I had a popping noise on my tj once. Turns out my rear track bar was as loose as can be. I could literally remove the nut with just my fingers.

Thanks a lot, that was the issue. Took out the bracket, luckily it also used the stock bushing, and put it back in its stock location. No more popping or grinding. Also put it in 4H and 4L works perfectly. Thanks everyone for the input.

Good to hear that's all the problem was.

Now since Rolly suggested it, you can add alternate shifting arrangements to your wish list...
