Measuring Acceptable End Play STEP 1. Using a magnetic base, mount the dial indicator on the spindle end, making sure the hub face is clean and free of gasket material. STEP 2 . Adjust the arm of the dial indicator, setting the plunger tip of the indicator on the machined face of the hub at the 12 o’clock position.

The easiest way to test whether your trailer wheel bearings are too tight is by moving the wheels on the trailer. You want to move the wheels from side to side. There should be a bit of movement, but no more than around 1/8″. Anything less than that, and the bearings are too tight.

The wheel end should be raised to check for noisy or loose bearings and fluid condition. The outside bearing should be removed and inspected, if possible, based on the hub design,” Hogg said.

Dial indicate wheel end to verify proper end play of .001" to.005". STEP 6. Verify the wheel end has smooth, quiet rotation. STEP 7. Inspect for any wheel end abnormalities. STEP 8. If, during an inspection, a notable concern arises, disassemble the wheel end and replace the wheel seal, lubricant and any other components as needed. STEP 1.

The outside bearing should be removed and inspected, if possible, based on the hub design,” Hogg said. “The overwhelming benefit of an annual inspection is to readjust the end play or to simply re-torque the retaining nut.”

2024年9月20日 · Measuring wheel bearing end play is a vital step in identifying worn bearings and preventing potential safety hazards. Excessive end play can result in: Increased Noise: Worn bearings can produce a rumbling or grinding sound, especially at higher speeds.

IMPORTANT: End play can be checked with drum brake installed or removed (preferred). If installed, ensure all brake drum wheel fasteners are installed and tightened to manufacturer specifications before checking endplay. 2. Ensure hub hubcap mounting surface and end of spindle are clean and totally free of any burrs or debris. 9.

Using a socket wrench, remove the lug nuts and lift the wheel off the ground. 3. Mount the Dial Indicator. Attach the magnetic base to the wheel hub near the bearing.

for seal leaks, smooth rotation and end play. In addition to the intervals listed below, these inspections should be done at each brake reline, 1. Park the trailer on a level, debris-free surface. 2. To prevent the trailer from moving, chock the wheels of the axle not being raised. 3. Using a jack, raise the axle until the trailer
