I have an 01 supercrew 2wd. I put new brakes, shocks, rotars, bearings on front and new shocks on rear. I took my first set of 20 inch wheels off the truck and put on a new set. I then leveled out my truck by dropping the rear with shackles 2 inches. Went and got it aligned due to diff ride height and new shocks etc. OK the serious part. My steering wheel shakes like it is about to take off to outer space, and I have a bunch of road noise. It starts at about 30 mph and won't stop until maybe 75 or 80. Out of balance wheels/tires right? nope. They have been balanced 2 times and I even bought new tires thinking it was the wear on the old ones. Still shakes like crazy but the road noise is pretty much gone due to higher quality tires. Has been going on for about 6 months and is driving me crazy. Has anyone heard of this problem happening after installing lowering shackles etc.? I need your assistance please.

 

you probably have something wrong with front end. check to make sure your bearing aren't loose. or anything else in your front end, tie rods, balljoints. Jack up ur front end with the susp. drooped in shake your tires up n down n side to side to check for play.

 

sounds like bearings are loose repack and tighten them fingertight but snug

 

Nice call. It was the bearings. I thought for sure since I had just put them in they would be good. I just adjusted them etc and now all is working perfectly. Thx for the imput.

 

your welcome bro

 

i dont mean to jack the thread, but i might have a similar problem although no shaking on my end.

i used to run 235/70/17, but switched over to 265/70/17 (general contitracs?). anyway, ride was okay and didnt have noticeable humming. after those tires wore, i switched over to wrangler hp (the one that came on escalades?). i then noticed obnoxious humming coming from the front end. i thought it was the tires because all reviews i read led to it. just to note i didnt get an alignment when i first switched over from 235 to 265. anyway, i recently bought new tires hoping the problem would go away. sadly, it's still there. was there anything damaged over the course of not correcting my alignment? inputs appreciated!

 

what leveling kit did you use ... some kits if you go with too steep of an angle it can cause premature wear on parts (cv axles, balljoints) just check everything over and see

i have a HBS 3 inch front spacer and i have no problems at all on the stock 275/55/20s
