okay i had one of my wheel bearings changed about 3-4 weeks ago but now i hear that humming sound again when i accelerate,also a shaky feeling when im idle like at a red light, can the shaking be from the wheel bearings and what else can a bad wheel bearing cause, i have a 2001 pontiac bonneville sle with 65,000 miles on it.
new spark plug wires will help considerably
Take it to the GM-Pontiac dealer. Seems the job wasnt done rite if you get the same bad sounds.
broken Torque wrench perhaps? Lol The rotor is tousled with the aid of fact the axle nut wasn't retaining it in and it became wobbling against the nut and warping itself. have you ever tried getting a sparkling axle nut? you have gotten screwed up the threads on it with the aid of broken torque wrench. you could additionally would desire to substitute the hub to boot in case you broken those threads. additionally as each and every person else is saying, there's a cotter pin hollow for a reason. :)
A bad wheel bearing won't affect the car when it's not moving, so the shaking at a stop is something else.
A bad wheel bearing CAN but (unlikly) cause the car to shake very little at idol it would have to be in extremely bad condition it can cause the ABS and tcs lights to come on if equipped and it sounds like they didn't correctly install the wheel bearing and or used a cheap wheel bearing or put a used wheel bearing on and if they just replaced the wheel bearing itself and not the entire wheel bearing hub assembly a bad wheel bearing hub assembly will keep ruining bearings and the 98-03 Pontiac Bonneville and grandprix's are bad about going through wheel bearings and wheel hubs I would take it back to the mechanic that replaced the bearing right away their should be some type of warrenty on the bearing through the mechanic or the manufactur of the wheel bearing as long as it wasn't a used bearing from a salvage yard take it back to the mechanic that installed the bearing and if they claim nothings wrong with the wheel bearing and or the bearing hub assembly take it to a GM dealership or any certified GM mechanic!
