i just put 5mm eibach spacers on the front wheels and now im getting a vibration in the steering wheel from around 55-65mph..i feel it in the pedal a little too...the spacers came w/new studs so i put them in too...why is there vibration??

 

Get an alignment. It throws the toe (I think) off. I had an alignment done and the vibration is gone. Also after a couple of miles, retorque the lugs.

 

whats the tourque specs for the wheels?

 

Ehh, I have no clue.

 

perhaps the studs arent "seated" all the way, if theyre not pulled all the way into the hole i suppose they could be able to wiggle. even the smallest amount could cause vibration

 

torque specs on most nissans are 80-90 ft/lbs, get an alignment then go get your front tires rebalanced, also double check the studs, also, did you put the spacers on with your OE wheels or do you have aftermarket, alot of aftermarket wheels need hub rings, without hubrings you could experiance vibes...but it doesn't sound like hub rings is your problem since you just now getting the vibes after the spacers and didn't have it before.

BTW: discount tire will balance you tires for free... and can help you if you're still stumped...

When you put the spacers on it pulled you rim off the stock hub ring, these hub rings keep the rim positioned on the hub to minimize vibration. I don't think that you can buy aftermarket hub rings to work with the new spacers. Some of the larger spacers come with hub rings machined right on them, but I think they start at 10MM. I'm pretty sure the vibration isn't coming from the alignment, it's the spacers. Take them off, and I bet the vibration goes away. I did some major research into spacers as related to a new set of rims and learned a bunch. I hope this helps.

 

90 to 95 ft.-lbs.

 

i dont quite understand when you said "when you put the spacers on it pulled you rim off the stock hub ring"????.....i have aftermarket wheels on for about 1.5 yrs...i just put the spacers on....is there a stock hubring that comes off...or is it just part of the hub itself??

 

purpose of hubrings is to make up for the gap in the center bore of the wheels, OE wheels shouldn't have hubrings because they manufacture the wheel to fit perfectly over the center bore, but many aftermarket rims have a slightly larger center bore...hence hubrings

if you had hubrings they are either stuck around the hub in the picture above or they are stuck in the center bore of the wheel. they have a flat larger side that goes facing the hub. and the smaller side should fit tightly into the center bore of the wheel. if the spacer causes the hub ring to not be in contact with the wheel and there is a gap then that will cause the vibrations

 

Very well put. So, if you are to use spacers on your front wheels, is there no way around this, if you use 5mm spacers or something that doesn't come with machined hub rings? Unless, I suppose, you can find aftermarket rims that come with the correct bore size.

 

are your spacers laser cut?

 

discount tire carries the most common sizes of hubrings and they can order anything under the sun, to fit pretty much anything under the sun. its unlikely you will find an aftermarket rim with the correct center bore of your hub, most manufaturers will make the wheel with the correct bolt pattern and include a set of hubrings with the wheels. if you're going for aftermarket rims you should look and find one with an offset that will line the wheel up where you want it in relationship to the fender and not even mess with spacers. but in some situations you can't avoid spacers.
ex: a co-worker of mine has a camaro and bought Z06 wheels, he needed spacers so that his tires wouldn't rub because they were such wide wheels.

each situation is going to be different depending on your setup, but my opinion is just to try and avoid spacers if you can, there isn't anything wrong with them but to me it's just something to worry about.

PS: sorry for long post

 

The 5mm spacers are small enough so the stock hubs still stick out a bit. Try the alignment and see if that works.

 

I agree that 5mm is small but the hub bore on most rims have a taper on the hub side of the rim which won't completely seat on the hub. I tried all that already with my new rims and had no luck. One option is to get a spacer that is larger and has a hub ring already machined on it. Then you have to worry about the offset and how far out the tire sits.

 

Your are having some kind of crap luck, first the 300ZX bbk now this, the Eibach spacers should be hubcentric, did you buy them new specifcally for your car? You should have hubcentric rings for your aftermarket wheels? If you don't that's where your problem lies, alignment is a good thing but probably won't solve your problem, pushing the wheels out wider amplies the vibration, with no hubrings depending on the hub diameter of your rims you may have had only a slight vibration that wasn't really noticable but with the spacers it became so. If you do have hub rings did you remove them before you put the spacer on as sometimes they don't stick in the rim but will stick on the hub of the car. Take the wheels off and see if you have the ring in the wheel if not, there's your problem.

Also for the first 200 miles you will need to retighten the wheel nuts to 80ft/lbs every so often, hope this helps.

 

The manual says 72 ft/lbs.

 

Thanks..yeah i've had no luck here...now my wheels never had hubcentric rings...when i got the wheels they came w/a note saying if there is vibration i will need to get the rings...but i've had no problem until i just put the spacers in...so i dont know what to do first to try to fix the prob

 

hub rings arent $$$, just pick a set up and see what happens.

when u take the spacer off the vibration goes away right?

 

you dont need to tighten that much.

 

You are so right! I have done my own research and came up with the same conclusion. Anyone can go to eibach or H&R site and see the description of hub centric for 5 to 8 mm versus 10mn and plus spacers. How about a 3mn spacer? It is small enough to leave enough room on the hub for the rim to sit on it? I might be close!

 

I'm not sure if you could find a 3mm for our cars, I can't remember. I don't know if 3mm would give you enough space for the rim to seat on the hub enough. Also, how much will 3mm move out the tires... it would be a little but I don't think it would be enough for the potential hassel. Your thinking in the right direction though....

 

Sorry to say... ditch the spacers. I'm sure that the problem will go away then.

 

95 ft lbs. is way too much . That will lead to warped rotors.

for years Ive stuck to 65-75 ft lbs.

 

not to mention maybe snapped studs, my (old)tire place over tightened and downt he road several studs snapped, almos tlost the whole wheel. scary stuff. ended up making the brake wobble and took out the caliper and just turned into a mess.

 

i work at discount tire and we torque max's at 80 ft lbs

 

The manual reads 72 ft/lbs.

 

Manual reads 72-87 ft/lbs.
I always thought it was 80 for some reason, but I guess that's still within spec.
