Exclamation shakes/vibrates at 60-70mph

hello all,
last year i brought my truck to a mavis and they put new tires on, alignment etc.. alignment was awful it pulled hard to the right. So I brought it to small time shop thinking they had more pride in their work and they would fix the alignment. alignment came out better but when i approach 60-75 mph the steering wheel and floor boards shakes and vibrates violently. wondering why this can occur.. they fixed a leak in the front differential, new ball joints in the front. new U joints in the rear. new sway bar links, tires were balanced.. this WAS NOT occuring before i had this work done.. i believe somewhere in the process of aligning it, something got screwed up. thus my issue here. shakes and vibrates from 60 to 75 then even worse when coasting at those speeds..
scary stuff need some help.
rim size 15
goodyear tracker 2 tires are worn, have one summer left before snow

thanks

Default Re: shakes at 60-70mph

Could be a tire/wheel balance problem. Could be a bad tire and although it may be *balanced* as a machine indicates, if it's got an issue such as out-of-round, no balance will cure a significant physical defect and a vibration may be felt. Could be a bent rim making it shake, again, balance can mask but will not fix that depending on severity. Could be a wheel bearing. Much of the answer to the next step depends on who is going to do the work, you or a shop.

*Edit: would have been helpful to tell us if it was shaking before all this work was done, or if a new problem was introduce because of it. Also would have been good to mention if tire and rim size are OEM or if altered, as would be anything else not OEM in the vehicle suspension.

Not to hijack your thread but I have a very similar issue, I have no "shaking" of the wheel or anything, but I feel a very strong vibration through my pedal/floorboard starting at about 45 mph and gets worse as speed increases. Putting windows up at high speed results in a really loud hum, as if I had boggers or something. This has developed recently, seemingly out of no where. Replaced wheel hubs, tires have been balanced/rotated/checked for damage, but the issue persists. Running on 33 x 10 BFG AT's, 15 " rim. 4wd, 3 inch body. Tires have been on the truck over a year, this issue just developed in the last week or so. Thanks for any help!

Installed recently:
MOOG upper control arm/bushings
MOOG lower ball joints
OEM front hubs both sides
OEM leaf springs/u-joints
Pro-Comp shocks

All of these were installed well before this issue began, aside from the passenger hub which I thought may have been the culperate (wasn't).

Again I do not feel any vibration at all in my steering wheel or the handling of the truck, just a strong vibration (and hum with windows up) at highway speed
