DPKetchum, and whoever else is out there here are my results of last Wednesday's meeting with factory reps. First I show up at 9:50 for my 10:00 appointment , Well at 1:50 they finally show up, good thing I took off most of the day from woprk ,huh? For the pull to the right the truck is within specs and checks out fine with dild* head behind the the wheel half the time, says D/C most likely will come out with adjustable caster bolts in the future and we can try that out when the time comes. DRONE after I leave the ????ler I go directly to the exhaust shop to have my Magnaflow 17223 (?) and 4" downpipe installed, now it sounds like my '97 did Oo. After the exhaust shop I go home and in an hour am on the road to get my B&W GN and 5er hitches 2900 miles in 3 1/2 days No DRONE any more to speak of but betwen the fan clutch and the A/C I still get the vibration coming and going. Removed my bugscreen thinhing it was blocking airflow bur still there, start playing with the A/C button and what a racket when that kicks in anywhere from 1700 -3000 RPM's in 6th. Inclined to say it is A/C related. I'll back off for now!! Mark
