2" BDS lift and vibration...mpg?

Well, I did the BDS 2" lift...remember this is my daily driver...CJ is for fun.
My questions are...
-Is the increased vibration normal, and will it get better as it "settles in?"
-Why would my steering wheel be off-center now?...the guy told me to bring it back after 200 miles or so after everything settles...did he screw up or is this normal too?
-Any ideas what the lift and 31x10.5 tires will do to gas mileage in the HO 4.0L automatic?

Thanks so much,

I have a BDS 2" w/ 1" shackles and have no vibration!(even @ 75 mph )
Check and see if theres angle shims between the spring seat on the rear axle and springs. Is there a transfer drop kit installed?
And for the steering ,a drop pitman arm .
My steering is off location too, I don't fell any differents in the drivability or I'm just use to it! I'm planning to install one though.But not sure of dim. for a 3" lift?
Takeing it back after 200 miles is to retighten all hardware. (My U-bolts were loose after 100 miles).

I had BDS 2" lift put on by my local dealer @ 1 and 1/2 months ago. It gave me 3.5" of lift, and has not settled at all yet. I get a little driveline vibration. We did T-case drop, but not degree shims, as it said was not necessary on 2" lift. They said to bring it in in 350-500 miles to check tightness of everything. My steering wheel was off center, but still drove straight, they said the lift instructions said it might need to be re-aligned after the install, we did that, and wheel is back to center now. I'll be bringing it back in to check everything in about a week, so far everything seems ok. I have a 4 banger, and I put on 31x10.5" tires, my mileage (city) went from about 20 mpg, to 18 mpg.
Happy trails,
