i just had my wheel bearings dont..(both fronts)....my buddy did it....hes a mechanic and so is his dad...he came over and torqued the bolt in the bearing (axle bolt) this afternoon....its not a noise really...its just a feeling...almost like a pulse.....my rotors are new....i looked...the nut is on good...i took it for a drive....it still has the same number of threads showing ( about 4 threads)....on both sides...and my buddy said my brakes were dry (i did a brake jon about 4 weeks ago and used a little lube...but i have had them off two times since...)...so i guess this is possible...i dont really feel it when im going 45 mph +....doesnt seem to matter if my foot is on the gas or not....i was wondering if i should greese something? i got some greese stuff...and some lube from walmart to use if you guys thinks its just dry brakes...but whats the best stuff to use? ....its a long questions but sorry....and also...there new rotors...so thats not it...and also doesnt seem to be shaking at all....thanks and God Bless--Nick
