Let's sift through every square inch of a 2013 Tahoe PPV

Pictures are finally uploading.



Are the relocation brackets supposed to be swung out like that? It’s the only way they fit.

It actually wasn’t that big of a drop compared to stock PPV height.

Anybody have input on the trailing arm brackets? I’ll probably email DJM.



I’ve been busy trying to get my Audi project done before winter. I’m going a little bit overboard in some regards and spending time on lots of silly little details.

20 pounds of boost with AWD and a manual trans sounds like a whole lot of fun in the snow.

Those brackets are supposed to be bolted to the axle not hanging down like that. I'm not sure if I have any good pics... I will look.

I started out with the flat portion bolted to the axle, but it was literally several inches away from the trailing arm.

It's physically impossible to bolt the brackets up any other way.

The only way to make it work that way would be to use extended and/or adjustable trailing arms.

Sounds like your axle needs to rotate (change Pinion angle) in order to line up properly.

Mine are bolted flat to the axle and everything lines up with stock upper and lower trailing arms.

I'm confused.

Wait... I get it now...

I had my jack stands under the axle housing because I wanted the suspension loaded for tightening bolts.

What I need to do is jack the rear up by the frame and let the axle hang.

Any updates?

Any updates?

YES!

When I went to reinvestigate, I immediately noticed that the problem had corrected itself.

Just from moving the Tahoe a short distance to park it, everything clunked back into place. I just need to put the bolt back in on each side, and I'm good.

Now I need to do the front struts, sway bar, tie rods, and upper control arms. The floorstanding strut compressor that I ordered from Jegs should be here in the next couple of weeks.

Lots to report…

I’ve been doing the front, and documenting with pics… BUT… I decided that the original strut bumpers needed to be replaced. At first I planned to just clean them and reuse them, but they were becoming brittle.

My dumb ass threw the originals in the dumpster before I checked the part number. I tried my best to figure out which strut bumpers were appropriate, and I still don’t know if the PPV used different ones in the front or not. I ended up ordering the ones from DJM, just because it seemed like the safe bet since I’m using their coil springs.

As I’m working on the Tahoe, I’m simultaneously driving like a dick in my Challenger, and this happened:
