issue after leveling, and other ???'s

[frankenstien]

ok so i have a 2006 yukon xl denali, was bone stock with 2 blown out rear air shocks.

i put in z71 surbuban coils int he back with 1.5'' spacers, new shocks, new torsion keys, and shock extensions on some stock length monroe shocks

i did the pull the battery cables, pull the RTD 30a fuse, re connect battery, i am not getting any of the service lights or warnings

this is my problem, when i turn like from a stop sign, left or right, and even just give it a larger amount of go pedal, its screeching what sounds like the front tires, also on a dirt road, if you hammer it the front end gets all squirrly,

my tires only have 6k miles on them, they are cooper discover at3 on a 17x9 wheel 265/70/17

does anyone have any ideas as to why this is doing it?

does the RTD fuse have any effect on the Awd system?

also i have an alignment scheduled for monday, it was a little off before the install.

thanks

I just lifted my 2001 Yukon XL also with Cooper AT3 265 75-16 but mine is part time 4x4.

My keys are not cranked 1 inch spacers in the rear measurements from ground to fender well lip 37.5 front 37 rear.

My did not make any noises I drove it about 40 miles before it was alignment was done and no issues before of after the alignment.

I am planning to go with some longer spacers to get the back end a little bit higher than the front.

Question for you how much lift did the Z71 springs give you I want at looking 1 more inch of lift.

But I have noticed it has a better ride though the bigger bumps and chuck holes due to the longer travel and not riding on the bump stops any more.

Driving over the stutter bumps on the HWY you feel them more due to the Torsion bars cranked up being stiffer.

I read others complain about the extra swaying in the cross winds and in turns yes a little bit more but not much to worry about just slow down a little more for the turns.

Hmmm mine is at 39 5/16 rear and 37 5/8 drivers and 37 1/8 passengers, to accomidate fuel and driver.

From what I looked at the z71 springs are worth about a half inch, I didn't measure my rear wheel well height before I started,

It has a bit of sway but not bad, going to put a set of eibach sway bars on it though, the wife drives it so I want it to be as good as it can

Here's a pic of it

Also, after some more driving it doesn't do the screech all of the time, but its defiantly the front tires, maybe because the torsion bars are stiffer?

Even on pavement, making it downshift at lower speed even on pavement the the front tires spin

Anyone else have similar issues? I'm more worrying about winter and the front end running away.

I was also thinking about wiring in the resisiter kit I bought that is supposed to lie to the computer and make it think the shocks are still there, and put the RTD fuse back and see if there's a difference

The RTD fuse has nothing to do with the AWD system. The only screeching that I'd imagine would be happening when your nailing the throttle is tire spin or your tranny is slipping.

If your nailing the throttle from a stop while turning (why?) your spinning a tire I'd imagine.

If you raised the front end, then the alignment is perhaps way off.

 

[frankenstien]

the alignment was in fact way off lol, had about 3/4'' toe in, he said that wasnt good and all the cambers were over 1 degree off, i dont know much about alignment specs, but the truck handles how it should now

missed a few replies apparently, wasnt nailing it from s stop/turn, the alighnemt was way off, its smooth now no screeching or darting

ah well yeah alignment being way out could cause that!
