First- Something heavy is boucing around under my car.
Whenever I go over a bump that cause the front of the car to jump a bit, there is a very heavy oscillation for a split second, it feels like I'm going over the bump twice.
It's most promenant if I'm going over a speed bump slowly, when the front wheels go over, and the front of the car goes up and down quickly- there it is...I can feel it through the shifter too. Feels like the engine is loose.
It happened before, turned out my passenger engine mount was totaly seperated, I could lift the entire passenger side of the engine!
Anyways, I replaced it, and it went away completely. Now it's gradually come back, BUT the engine mounts are fine!!
It doesn't feel like the shocks... it fels heavier, clunkier (but not like metal on metal) and more centralized than the wheels.
Any opinions????

Second- my passenger side front wheel grinds/hums a bit. It's not a constant sound, but more of a thubthubthub as the wheel rotates
It's fine if the car is offf the ground, and I'm turning the wheel.
I wore my brake pads down accidentally, and dug into the rotor pretty bad, so I assumed that was it. I replaced the rotor yesterday, and it's still there!!! The bearing seems fine, and the races are smooth.
If the bearing is very tight (like, lots of weight on the wrench tight) it isn't as bad, but then the bearing hums/growls pretty bad.
If the bearing is looser, it only makes the bad grinding when I am turning to the left... if I turn a bit to the right, it ALMOST COMPLETELY goes away, only while turning right. So- only grinds when going straight, and a little worse when turning left. (with a loose bearing)
Oh- NO DIFFERENCE whether the brakes are on or not.
But, any looser with the bearing and the wheel would fall off.
Sound like inner bearing? Outer? Races? Bent hub spindle?
Come to think of it, I did crank that wheel off a curb a while back, hard enough to make a little gouge in the rim, but that's all.
Anyways, it's really pissing me off, becuase you can feel a grind throughout the whole car.
How the hell do you replace the inner bearing anyways? It seems larger than the inside of the end of the hub!!

Thanks for any input guys!

 

are you sure it is coming from the front passenger side? bearing rumble is usually very decieving and often sound like it is coming from different places, check all your wheels.

 

Checked them all...
Replaced all the pads too.

 

#1 try tranny mount. just a thought.

#2 defineitly a bearing, but like hyperdaddy7 said, it could be in anyone. they tend to hide the sound. it's odd that it does, but it does.

 

Yep, tranny mount or something is my next check.

Well, I just orderend the front outer and inner wheel bearings. I'll see if that makes a difference.

 

Changing front wheel bearings is soooooooooo fun. SIKE!
