Should there be a slight amount of play in the wheel bearings?

    My car is up on jacks the wheels are off the ground Im checking the play in the wheel bearings. Someone said there should be no play whatsoever if you grab the tire top and bottom and try to wiggle it. The manual says not to make it even finger tight. The cotter pin holes in the spindle shaft are a few degrees apart and turning the nut to the next spindle hole will make it too tight.

    Please advise.

    Does the play go away when you spin the nut to the next slot? And does the wheel still spin free when you spin it to that point?

    yes it goes away and yes it still turns, I dont know if there is any resistance but the manual is clear not to tighten it finger tight. Any idea? How do you set yours?

    The reason I ask is because they said at the alignment shop that the bearings were loose and it would affect my alignment. They aligned the car and they showed me on the screen that it was in alignment but i notice when i drive it tends to go to the right when i take my hands off the wheel.

    Jiggle the wheel as you spin the nut tight with your hand. The "play" should go away. If it doesn't, then....well, bearings are cheap.:Do No:

    I'm sure there will be other opinions on this matter, though.

    Gary; it should have a slight amount of play if u wiggle tire at top & bottom. The car should not pull at all if it's aligned right. When u align front end, u have the weight on the front end and if there is slight play in bearings, it wouldn't make it pull at all. Did mine with bubble leveler on flat cement and it runs straight as an arrow without holding the wheel. Yes I have a slight bearing play as suggested in the service manual. Also added caster to 3/4 * on left and 1* on right. (This is to compensate for the crown in most roads). Camber was set at 1/4*positive on both L & R. Put all new Moog front end parts on as well.

    so is my car going right because they didnt add caster to account for the road crown? I just paid for an alignment, they showed me it was within spec but it pulls right. What should I do?

    Did you align your car without a computer alignment? I didnt know that was possible? How do you get the degrees right? Wow.

    Hey did you double check to make sure that you have equal pressure in your tires??

    Or take the front tires and swap them left to right and see if the car pulls the other way. The pull may be in the tires. Think about how a dixie cup would roll if placed on its side.

    A slight amount of play in a wheel bearing is normal. I loose bearing will go all day. A bearing that is too tight will fail in no time. There's a "feel" to it. I take a cresent wrench on the castle nut and spin the rotor or drum as I just snug the nut. Then I back it off till the first hole in the spindle gets exposed.

    And never re use cottor pins!

    Hi,
    My manual says to torque the wheel bearing nut to 19 lbs while turning the wheel, back off the nut and re-torque to 11 lbs. If the spindle hole lines up with one of the six slots in the nut, back off until the next slot is in line with the hole, If neither spindle hole lines up with a slot back off nut no more than 1/4 turn until a slot is in line with a spindle hole.

    Is this a Buick manual? my manual says in bold caps "UNDER NO CIRCUMSTANCES IS THE SPINDLE NUT TO BE EVEN FINGER TIGHT."

    it says looseness wil have .002 to .006 inches of end play.


    So when you tigthen them are you saying you hold the nut in place and then give the rotor a spin and wherever it stops you go to the next looser cotter hole?

    This is interesting - I looked this procedure up in both my 58 and 71 chassis manuals. They describe it completely different from each other. The 71 says exactly like Gary said above, with .002-.006 end play. The 58 manual specifies 30-110 INCH pounds of torque. If an in.lb wrench is not available, then tighten nut until all bearing looseness is removed, then TIGHTEN nut to the nearest of the two cotter pin slots. Bearing preload must not be more than 1/12 turn of spindle nut.

    So the two manuals contradict each other. They are set up exactly the same, except the 58 is drum and the 71 is disc. Would that make a difference?

    I've never had an issue with bearings going bad after I reinstall rotors on any of my 71's...and I always remove all play. I guess .002 end play is hardly noticeable:Do No: But I've never used a wrench to tighten the nuts...just finger tightened until all play is removed, then fin the nearest cotter pin hole.

    Hi Gary,
    Are you sure your referring to the info I gave, I didn't make reference to finger tight:Do No: or spinning the rotor till it stops.
    The first paragraph in my manual states, A properly adjusted wheel bearing has 0.002 to 0.006 end play in the hub and a loose nut when adjusted in the following manner.
    Then it follows on as I quoted before.
    Thanks Bruce

    Doesn't the 58 have angular contact ball bearings and the 73 angular contact roller bearings. my 54 Chev was tighten in the same manner as your 58.

    Bruce, you are correct. I didn't think about the type of bearing.

    with disc brakes you want just a little play.this helps push back the caliper piston so there is no drag on the brakes.

    I wasnt referring to anything specifically just saying .. just saying finger tight is too tight but the guys that did my alignment said i have play in my b earings and it will throw my alignment off so I didnt knwo waht to do. Theres play in my bearings turning the castle nut to the next available cotter hole would require me to tigthen the nut to finger tight whichh is forbidden. waht to do. Maybe the wiggle is normal and these guys were trying to leave a way out for their alignment work or wanting to do a bearing and lube job I dont know... but the car does pull to the right and I want a straight as an arrow 'you dont see this kind of alignment anymore' kind of alignment. I bade 60 bucks for the alignment and its not straight. im still mad at that service manager for raping me out of my hard earned dough for something for nothing shop fees and add ons that were misleading but i digress. The car is not straight thats my problem and i want to know if theb earings are causing this. At first they told me thats why my tires were wearing so badd, but there is hardly any play at all.. danyway..

    Gary, the pull you are experiencing may be in the tires, and not in the suspension.

    its very common for a car to pull because of the tires. Take the front tires and swap them left to right. Then go for a drive. I bet you the car will either go straight or pull to the other side.

    My money is that it will go straight

    Ok ill try it, ill take you up on that, i hope you are right. The tires are brand new. If you are right what is causing that ?

    I would suspect a belt pull.
