What is acceptable wheel bearing end play after adjusting using the TMC RP 618 procedures?

NOTE: Never use an impact wrench when tightening or loosening lug nuts or bolts during the procedure. The goal of this recommended procedure is to achieve a verifiable wheel bearing end play of 0.001” to 0.005” (. 025 mm to . 127 mm).

How much play should a bearing have?

Ideally, there should be zero residual radial play in the bearing to minimize ball skidding and reduce axial play (end play) so correct selection of the initial radial play is important. A number of things can alter the radial play during the fitting process.

What is the torque setting for wheel bearings?

Generally, jam nuts less than 2-5/8″ should be torqued to 200-300 lbf-ft; nuts 2-5/8″ and over should be torqued to 250-400 lbf-ft. See chart for exact torque specification. The final step is to use a dial indicator to verify the end play or free movement of the tire and wheel assembly along the spindle axis.

What is excessive crankshaft end play?

The total travel is the crankshaft thrust clearance. If there’s excess endplay on a fresh motor, it may be because the block and crank weren’t properly dressed or ground in the thrust area, the crank is bent, or the main-bearing thrust cap and journal are cocked (usually because the line hone is off).

What is crankshaft end play?

Crankshaft “end play” is measured as the clearance between the crankcase thrust washer and the axial mating surface of the crankshaft (see Figure 1).

What is axle end play?

In a differential/mechanism for transmitting power from a drive shaft to the axle shafts of a motor vehicle, an axle shaft end play adjuster is threadingly disposed at the end of the axle shaft adjacent the differential pinion shaft. The end play adjuster limits the range of axially inward movement of the axle shaft.

Should there be any play in a bearing?

Ideally, there should be zero residual radial play in the bearing to minimize ball skidding and reduce axial play (end play) so correct selection of the initial radial play is important.

Should new wheel bearing have any play?

As a rule, there should be no perceptible play in the wheel bearing if you are pulling and tugging on a wheel 12 and 6 o’clock, but up to . 010 inch of. play in the front bearings may be acceptable on some old vehicles cars and trucks with adjustable bearings.

How tight should a hub bearing be?

Expert Reply: The nut on the spindle should be tightened until snug, with no side-to-side play in the hub and then backed off slightly, about maybe a 1/8 of a turn.
