Need help....Please

Ok, On the ride home today, my truck started actin up. If I hit a bump (patched hole, seams between lanes, or seams in the bridge) it will start making a grinding/vibration noise. (My guess is wheel bearings, but I dunno with these real trucks) And if I roll down the window, I hear grinding like something is touchin the rotor. I would normally guess wheel bearings, but I've never been able to stop a wheel bearing from making the noise in other things. Bad u joint? Bearing? Something worse?

sounds like a wheel bearing....when they go really bad they will pitch the wheel and rotor so hard the rotor will grind on the caliper shackle sometimes....but a bad wheel bearing can grind pretty bad just on its own too

I would jack the front end up. Then I put the front end on some jackstands. Then I would remove the front tires. Then inspect the ball joints, brakes, front suspension. I suggest this because it is basically free. Most likely you will find the problem this way. As it could be wheel bearings, or a bad ball joint or a combination of things. But the only way to find out is to do an inspection of the front end. If you find nothing wrong in the front then do the same in the rear. The rear is easier to inspect, as it has less parts. But you would need to inspect the u-joints, center support bearing, and brakes.

If you find nothing from your inspection. Then take it to a tire shop and have the tires ballanced and rotated. As you may have damaged a tire or threw a tire off ballance.

I'll take it to my shop in the morning, They'll run through it, I just want to know where to direct them. I've brought it to them 3 times now for problems with the front end. So far they've replaced sway bar links, and warrantied the sway bar bushings. I still feel there is something wrong. whats bearings normally run on these things?

BTW, I can also STOP the noise by hitting these bumps also. Hittin the brakes doesn't stop the noise. I either would have to hit a bump to stop the noise, or pull over, and it will stop below 30mph.

Thanks for the help. This one of those things that if you do one, you do them both?

If your going to do the wheelbearings. I suggest you do both driver/passenger side. Becuase if one is bad, the other is bad or going to be in a short time.

At $450 a pop, I just did the one that needed it. I'll do the other when it goes bad. It one thing to budget in order to buy mods, it's another when you have already spent the mod money, and you need a repair.

BTW, thanks, it made for a quick morning, went in, told em what I thought, and they weren't sure, told em to check it closer. Yup, bearing gone. Needed the whole hub assembly, and got the only one with a lifetime warranty, and it was from napa. Combine that with a lifetime warranty on the labor, if it goes again, I don't pay a dime, and I'm still ahead of the game.
