If each installation step is correct, wheel spacers won’t cause a clicking noise. If the clicking noise exists, here are some measures to eliminate it. Mostly, the ‘click-click-click’ sound is probably caused by the fact that the bolts were too long for wheel spacers. These bolts are going into the hub and touching the parking shoes. So, the first thing to do is to check out the shank length of the wheel bolts that you are using.
Generally, stock bolt length plus spacer thickness equals extended bolt length. Assuming the OEM length is 27mm and you add a 10mm spacer, then 37mm wheel bolts are enough to tighten the spacer and wheel. In this case, 40mm bolts will be too long. For bolt-on wheel spacers, check the thickness. Jack your vehicle and remove the wheel spacers to check whether there are any broken signs. If there are any, then changing to thicker spacers will be a solution.
Check If They Are Hub-centric
If it is not a bolt length problem, then check the hub-centric rings of the wheel spacers. Engineers design these hub-centric rings to fit perfectly the axle and the space inside the center bore of the wheel. This helps hold the wheel perfectly centered both during installation and road use. But every vehicle is different. If the hub-centric rings don’t fit quite well, the wheels cannot be properly balanced.
Sometimes the axle protrusion is a few millimeters longer than the hub-centric lip. In this case, these hub-centric wheel spacers will not sit flush against the vehicle hub. Depending on the vehicle hub height, there is a “maximum hub height” that the spacer is able to fit over. Giving an example, if the hub height is 10mm, then 8mm wheel spacers may not fit. BONOSS has designed different hub-centric styles to adapt different vehicle hub types.
Check Seat Types of the Wheel Bolts
When it comes to slip-on wheel spacers, a set of new wheel bolts is necessary. Since you no longer use the OEM bolts, it is important to ensure the seat type is correct. This is because if the bolt seat type doesn’t match the wheel lug hole, you may experience vibration. The conical seat set has a beveled 60-degree angled tapered shape and the ball seat ones have a rounded shape.
But even the rounded seats are divided into R13 and R14 types. Most Audi wheels use R13 wheel bolts while most Mercedes-Benz wheels use R14 bolts. Although R14 bolts look almost no difference from R13 bolts, slight differences can lead to weird noise. BONOSS has lined up proper wheel bolts for spacers, simply add up a set to the shopping cart. You don’t need to worry about clicking noise issues.
