Bad hub bearing

[LTb1ow]

What would a front bearing going out sound like?

A constant humming at higher speeds?

[FlyingDutchman]

from my experience in a fwd car, it was a loud hum an a slight vibration you could feel in the floor. If its just one side it will go away when you turn then come back when you straighten out. I drove from NC to NJ it was obnoxious lol

[deadtrend1]

Mine were making a grinding sound that i actually felt when I was driving it.

lift up the front end, grab the tire from the top and bottom, and see if you can wiggle it up and down.

My bad hub bearing made more noise while turning but also had a noise while cruising. If you jack it up and pull the wheel off and spin it you can sometimes feel it. Pull the pads out of of the caliper and put the rotor/wheel back on and spin it freely and you might really be able to hear it.

[LTb1ow]

Well the sound doesn't go away whether or not your are on the brakes.

:nod: do this. if there is play up and down, its more or less your hub bearing. don't you have some bald tires all around? could be tire hum + unbalanced. if you want to check them hit me up!

[LTb1ow]

Well its on the list o things to check out. How hard is to replace a hub bearing?

[sweetbmxrider]

depends how it all comes apart :D its a sealed unit in the front so it just bolts up! nothing you couldn't handle in the driveway.

Including the five lug nuts, there are a total of 13 nuts/bolts that are removed and then replaced when changing a hub. Jack up and support the car. Remove the wheel (5 lugnuts). Remove the caliper (two bolts). Remove the rotor. Remove the caliper bracket (2 bolts). Remove the hub (disconnect wss and 4 bolts). Installation is the same process in reverse. Be sure to torque and use blue locktite on the 9 bolts that secure the hub, caliper breacket and caliper. Total time using hand tools 45 min-1 hr. Note: Some people leave the caliper attached to the bracket, but this can make slipping the cliper and pads back over the rotor a bit more difficult ( a matter of personal preference).

w0w this guy's good

[1QWIKBIRD]

whatever you do....replace them in pairs.....and send me the old ones.

I might need them as cores.

[JL8Jeff]

Plan on the hub being rusted into place so even after you remove all the lugs and bolts it might not move easily. Have some PB Blaster ready, a heat gun and a decent hammer.

[LTb1ow]

Fannntaasiiic.

I hope its the wheels.

Probably right about that. Hubs only last a few months (at most) on my HPDE car so they don't have time to develop any rust. Takes me longer to press in the ARP studs than it does to change the hub usually.

[BigAls87Z28]

Havent seen that much rust on any hub bearing, nothing that a BFH couldnt take care of. On your car, you dont have to worry about the CV axle, so a tap here, tap there, and plunk onto the ground.
PB Blaster couldnt hurt either...

Hub bearing will hum around 30-40mph, and get worse when turning. Make sure when you are checking it for up and down movement, that if you do notice movement, that its not the ball joints, or if you try side to side, thats its not the tie rods.

[LTb1ow]

I am hoping its the tires and as soon as I get the money will be replacing the backs with DRs and moving those tires up front.

[sweetbmxrider]

so you will replace bald humming tires with bald tires? ahha!

[LTb1ow]

Nah, the rear tires are fine. Lots of tread, just sucky thread for launching...

[sweetbmxrider]

oh....well sweet!

[LTb1ow]

Yea, wanna mount a pair of DRs for me?

[sweetbmxrider]

sure. got beer? haha whenever you get them. mount some tires, play beer pong somewhere, leave you in a random house :lol:

[LTb1ow]

Sounds like a plan, prob won't be for a while now. :(

[sweetbmxrider]

yeah its a bummer. well whenever, i'm down.

[LTb1ow]

How hard is it to do?

I really need tires on the fronts, I was thinking of getting some cheapos ...

[sweetbmxrider]

20 minutes. its nothing when you have the equipment.

[LTb1ow]

Alright, maybe I will try and get some cheapos and some PBR for ya...

[sweetbmxrider]

:rock: PBR!!!!! yeah let me know. 275/40R17s? i could call

[LTb1ow]

Something to fit on a 17x9.5 rim.

[sweetbmxrider]

well thats stock size. they are going to be pricey. i would maybe look used.

[LTb1ow]

Yea, I have a set of the stocker salad shooters with tires but they look fugly as hell. We shall see.

[sweetbmxrider]

sometimes function > form

[LTb1ow]

Yea, I may switch back to them for the time being.

Can you remove a stamped on balance weight and replace with the sticky ones?

[BonzoHansen]

yes

[LTb1ow]

Sweet, I do not like them on my OEM ZR1s, and was yelled at for letting some one do that to em.

[sweetbmxrider]

what the hell is a stamped on weight? you mean a clipped on? balancing with sticky weights suckssssssss but its doable. just remind me.

you remove all of the weights anyways to rebalance a tire.

[BigAls87Z28]

Ohh, its not that bad. Little soap and water, scrub off the spot, and whao! Balanced.

Mounting/Balancing isn't hard. But to the people that have it down to an artform, they are the greatest tech you can have.

and to mount a tire...unless you like dragging a weight across a rim. :p

shhhhh i was going to sell him my wheels because his were "defective" with a large surface crack!

[LTb1ow]

Mine are OEM! Yours are replicas!

[JL8Jeff]

Mine are OEM! Yours are replicas!

OEM's are heavier than the replicas.

[LTb1ow]

Nope, OEM ZR1 are wayyy lighter.

[sweetbmxrider]

mine ss 10 spokes are oem, thats why i picked them up!
