Suspected bad wheel bearing

[ezza]

Im hoping someone can help me out here.

After a little overhaul i'v fitted a welded diff, solid diff bushes, solid subframe bushes, adjustable toe arms, big ass 12.25J rims (not sure if this is a factor, they are quite heavy), 10mm slipons and just some extended studs (the problem was before the studs though).
While driving im getting a bad wobble from real left wheel (wheels have been balanced), seems to become prominent around 30-40 mph, along with a dull almost grinding noise, kinda like humming.
When looking at the wheel while driving the lip seems to wobble in and out as if the wheel is buckled but they are brand new lips and the wobble doesnt happen every rotation like it would if the wheel was actually buckled, seems to be faster, like 2 times per rotaion.
If i jack the rear of the car up taking any load off it and put the car in gear the wheel spins perfectly true.

Does this sound like a bad wheel bearing?

Iv checked and double checked every nut and bolt back there and everything is solid (apart from what would apear to be bad diff backlash but thats a different story).

Any veiws/input?

thanks in advance

it doesnt hurt to replace wheel bearings lol

[!Zar!]

Easiest way to diagnose a bad wheel bearing is to jack the car up and try to press the top of the wheel in, while trying to pull the bottom of the wheel out.

If you can shake the wheel in/out like that and it moves, you definitely need new wheel bearings.

[ezza]

I tried this and couldnt notice any play^

[!Zar!]

Well if there is no play, then it isn't the wheel bearings.

[Devens240]

you sure your wheel isnt bent?

[brndck]

another thing to check is make sure your mating surfaces are clean. if you run a spacer, but theres a small rock or anything sitting under it, it may prevent the spacer from sitting flush against the rotor.

i dunno, i'm kinda reaching.....

throw the wheel on the other side of the car, and then spin it, if it still appears to wobble, then its most likely a wheel problem, not a hub/bearing problem.

[!Zar!]

Flat spot on the tire?

[ezza]

Il swap the wheels round tomorrow, il let you guys know if the problem is the wheel or the hub

[fliprayzin240sx]

Double check your lug nuts, might be loose too...

[ezza]

^first thing I thought of/checked

[ezza]

Flat spot on the tire?

Is there any sure fire way of diagnosing a flat spot?

[Silvia716]

Just cuz there is no play don't exactly mean its not the barring if there old the greese could be gone making friction when your driving first thing I would do is load em up with greese and see if that does any thing, and to check for flat spots just take off the tires and look at em there would be a spot with less tread than the rest of the tire usialy only happens to me from drifting

[Dustxking]

Take them to a discount tire or something and just ask them to spin the wheels for bends or flat spots in the tire. You could have a belt seperation in your tire.

[ezza]

The tyres are brand new, is this still likely?

[ezza]

Ok,
After swaping the rear wheels round I just had my dad drive the car forward and back do i could see if the problem was the wheel or the hub, the wobble has stayed on the passenger side which makes me think even more that it's the bearing.

Can anyone vouch for any particular make of bearing?

Thanks again

[blueshark123]

I am actually having the same problem on my daily altima i replaced my hub and bearing and it still feels like i have a bent rim which i dont. I will be replacing my rotors and pads this week to see what happens. I'm also going to put on some different rims to make sure its not that.

How is your alignment?

[blueshark123]

What you can also do to see if the wheel is wobbling is jack up the rear and put it in gear to see if it wobbles

My alignment is probably all over the place at the moment, its just set by eye, but surely this shouldnt be happening even with outrageously bad alignment.

gunna pick up a pair of bearings and have them pressed out/in

thanks tho

[Walperstyle]

Do you actually have a wobble, or are you hearing noise that sounds like a wobble?


I had a noise from my car, turns out it was a nut that backed off the top of my stance GR PRO SSD coilover, Every bump I went over made a horrible noise. I caught it, and tightened it down.

[ezza]

im getting noise and quite a prominent wobble, also i checked and double checked the coilover upper and lower bolts/nuts/rings/collars.

thanks for the heads up though

Clearly you don't know much about s-chassis. The bearings don't need grease. And also, SPELLCHECK.

Thanks again timken, or oem are the way to go.

Also, double check that the axle nut is torqued to the proper spec.

[ezza]

Il check the axle nut, i just cranked it up as much as i could without being silly.

and cheers, il try timken first

Well if there is no play, then it isn't the wheel bearings.

This is wrong. Read the thread I made a few months back. Hopefully that will help out.

I cant seem to find any rear bearings alone :s

they all seem to include the hub part which makes them pretty pricey

[95sx]

go to ebay and type in rear wheel bearings for nissan 240sx i just got my National bearings for $80 a piece

[ezza]

no luck, i litterally just want the bearings

[95sx]

that is all i ordered was just the bearings there is no way to just replace the innards of the bearings you have you have to pull the old whole bearing off and push the new whole bearing on

[ezza]

I want something like this:

Not this:

[95sx]

they are both bearings. The lower one is the only thing you can possibly order because once you start to push the old bearings off the inner race will pull off of the bearing and you will have to push that off too. they don't make the one up top for 240sx's as rear replacements. Trust me i have been dealing with that same ordeal myself for the last few weeks.

[ezza]

ahh, just wanted to make sure we were both talking about the same thing

damn, iv been seing the bearings alone for like £17 for older silvias, the full assy ones are like £50

[95sx]

yea i know kind of a bummer but its the way this stuff is lol

This is the way to go
RockAuto sells Timken's for $80 US dollars each

if you had the part number, you could order just the bearing
but getting the old one out and new one in is simply just not worth it

[ezza]

I have a mechanic friend who will press the old one out and new one in for free.

Would Nissan sell the bearings separate?

[zeebrah]

read this and laughed at how similar of a problem i had. for me it was the bearing some probably same for you... anyways check a yard if any near to you... u can get it cheap there. and just knock the bearing out with a hammer and place the hub part on some bricks. thats what i did and deff cheapest way. you want oem bearings. ive heard nothing but returning problems with EVERY aftermarket company. also depending if your 4/5 lug other chassis have same bearing. or even buy someones old 4 lug set up since they usually go cheap. hope this is some help

[ezza]

So the bearing itself does come away from the assy?

[zeebrah]

Yes. It just takes some well placed pounding or if u have access to a press even better... Forthat reason it's really dumb no one sells just the bearing itself

[Kaifd3s]

I bought a set from Ebay and they were just rebranded Ichiba assemblies. They are holding up just fine.

[RyanS13]

I had this same problem. Replaced the whole hub & bearings and problem went away.
