Hmm. My 2009 had thread, but it was slightly rusty. An impact wrench got mine in. Are you 100% positive there are no threads? Did you try putting the bolt in there without the suspension in the way?

I still haven't had time to put the rear shocks and springs in, so today I decided to push the rear axle up by hand until it hit something. Guess what it hit! The gas tank!!!! For some reason there part of the tank flares out at the top right over the axle. That is the part that the axle hits. Here is a picture of the scuff mark the axle made on the tank just by me pushing it up by hand.

Here is a picture of the empty spring perches when the axle is touching the gas tank. The tape measure shows 6 inches, so if your springs and shocks can allow your axle to compress this far, you NEED bump stops!

Here is what the wheels/tires look like when the axle is touching the gas tank. These are 17" wheels with 205/50 tires. It looks sweet, but, something tells me that driving with the rear axle hitting the gas tank could be hazardous to your health!

My car is a 2008 3 door by the way

That's strange there is no thread in there!! Must have been part of cost cutting.

this is interesting......

Lil Abner · 05-19-2011, 09:56 PM

What part of the axle hit that? The beam that connects both sides? I'm hoping to get mine on the lift tomorrow to see what I'm hitting...

Lil Abner · 05-19-2011, 10:19 PM

The tank hits with the wheels only that far up?? Hmm. My rear tires are that "tucked" just sitting in the garage...

Lil Abner · 05-19-2011, 10:21 PM

Well, I guess I'll do what you did in the photos with mine and see what's what. I'll try to post photos tomorrow night.

Autocross72 · 05-20-2011, 01:41 AM

Cool! I'll be interested to see what you find.

I also see marks where mine is hitting the gas tank. I put green tape over the marks for the pictures so it's easy to see where they are.

Passenger Side:

Driver Side:

This is the lowest point for me. I measured 11.25" center of wheel to the fender.

My problem is, my rear sits at 12.5" So that 1.25" of travel seems easy for me to hit. I might have to install some bump stops...

Autocross72 · 05-20-2011, 11:36 PM

Last night I was looking around and found that summitracing.com has several styles of cheap bump stops available. With just a bit of fabrication, the should work fine. My first priority, though, is to get my coil-overs installed so I can get the car back on t he road though. My Dodge 2500 cummins is beast, but is a bit expensive to use as a daily driver!

Lil Abner · 05-21-2011, 11:17 AM

Well, the stock suspension already puts the spring perch at a bad angle. Moving the axle position up just puts it back to factory.

But yeah, the downside seems that it's hitting the gas tank. With the the axle in the stock position, it will NOT hit the gas tank. It only hits due to the axle being higher. The spot it hits on the gas tank isn't the side of the tank, but the TOP flange.

dobbiedoo · 06-05-2011, 08:13 AM

What about adding a 3rd hole between the 2 stock holes?

miketejero · 06-16-2011, 01:11 AM

This has got to be the most "eye-opening" thread I've read so far. I'll look under my car about this. Thanks guys.

So I work at a new shop now that has a hunter laser alignment machine and put my car on it and checked the spec for the rear alignment after doing this mod. Surprisingly all my rear specs for caster camber and toe were all within green and very close to perfect. Its been awile since I had an alignment and my mods in the back are trd springs swaybar and this rear mod. So apparently shifting it does correct alignment issues from lowering the car.
