Message: <blockquote data-quote="astroboy" data-source="post: 353221" data-attributes="member: 4527">When performing off wheel and if u notice the mechanic put back all the weight to the exact same spot, that means your balancing was accurate before that and should not do the balancing at all, waste money. I only balance my wheel when replace tyres or re-mount tyres, otw, it should remain balance. Your steering and butt feel is a good gauge for whether a wheel balancing is needed. Those perform periodic balancing is I think waste money.Many times, many shops. I noticed all weights remove before performing on-wheel. Reason being off-wheel balance fail to solve vibration problem. More weights will be added while conducting the on-wheel balance, so that makes your wheel heavier and that's not good for performance.. and if you are lucky enough, after removing the weights, you will find vibration solved! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite9" alt=":eek:" title="Eek!    :eek:" loading="lazy" data-shortname=":eek:" />Some additional tips, once on-wheel is done, tyre rotation is no longer an option without performing another on-wheel after the rotation, maybe off-wheel too. But when it comes to just opening the wheel to replace brake pad, make sure the mechanic mark the screw so after replacing the pad, the wheel can be fitted back to the exact same orientation before removing the wheel, otherwise you need to do another on-wheel balance after the brake pad replacement. Anyway, its a good habit to always mark your screw so you are assured of putting back the wheel back with the exact same corresponding lug, some tyre shops don't do that for u, so u buta buta need to do another on-wheel once they put back the rim.Actually why vibration can occur to the drive terrain? I thought every rotating components in the drive terrain is balanced, so why vibration can occur? Drive shaft bengkok? <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite9" alt=":eek:" title="Eek!    :eek:" loading="lazy" data-shortname=":eek:" /> Brake disc rotor makan not even? On-wheel balance is actually the last option to rectify some problem in the drive terrain that causes the wheel to vibrate.</blockquote>
