How tight should wheel hub nut be?
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.
What is wheel hub torque?
Lubricate the wheel bearing with clean lubricant of the same type used in the axle sump or hub assembly. Tighten the adjusting nut to a torque of 200 ft-lb while rotating the wheel hub assembly.
How much grease is in a hub?
For traditional greases (NLGI Nos. 1 and 2), pump a ring of grease into the entire circumference of the wheel hub and coat the hub cap inner wall. The housing should only be half full of grease. Too much grease causes churning and higher temperatures.
How do you match a trailer hub?
First, click on your axle weight rating. Then click on your hub style (hub only, hub with drum or hub with rotor – for disc brakes). Then select the bolt pattern you want and your wheel size. You can then check for a hub that uses the same bearings as your existing one.
How tight is too tight for wheel bearing?
For context, the tolerable end-play for truck wheel bearings is the same: 0.001 to 0.005 inches, also expressed as 1 to 5 mil or 0.025 to 0.127 mm. In other words, it’s perfectly acceptable to adjust wheel bearings so that they are just a little bit loose, but not too loose.
How tight should you make a wheel bearing?
Can you put too much grease in a hub?
The housing should only be half full of grease. Too much grease causes churning and higher temperatures. Semi-fluid grease must be used with a vented hub cap. It cannot be packed around the bearing as it will slump.
What size hub do I need for my trailer?
The first specification to determine is the number of studs/bolts and the ‘bolt circle’ diameter. Most 4 lug hubs have a 4” bolt circle and most 5 lug boat trailer hubs have a 4 ½” bolt circle diameter. Cargo and utility trailers with 5 lug hubs are commonly found with a 5” bolt circle.
Does hub size matter on wheels?
Hub diameter is, therefore, an extremely important consideration when fitting new wheels, whether OEM or aftermarket. If the hub diameter is smaller than the axle, the wheel will simply not fit. Most aftermarket wheels are, therefore, made with larger hub diameters to ensure that they will fit on a wide range of cars.
How much do you torque a wheel bearing?
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.
Should a new wheel bearing be tight?
When It’s Normal. It can be normal for some wheel bearings to be stiff and hard to turn right after installation. That’s because some manufacturers pre-fill the hub units and sealed bearings with high quality bearing grease.
