How often do you repack wheel bearings on trailers or 5th wheels?
usually every 2 years or 6,000 miles
Rear bearings fail very rarely. It fails usually when you load your car over the limit, drive on bumpy roads regularly or tow heavy trailers. You need to change bearing only if it is causing problems otherwise do not worry about it. People have camries with over 200k miles and never change rear bearings.
I'd first check the balance of the rear wheels at a local tire shop. The one with the computer balancer. If the wheels are okay, then the rear axle bearings might be worth a check. The rear wheels also might need aligning though that's a tire issue. Not often, the wheel itself may be defective or the tire.
If there is an annual competition in your city, uniform wheels are often provided to all racers who pay the entry fee. Otherwise suitable wheels can be lawn cart or wheelbarrow wheels. The standard wheels are often simple axle-hole (bushing) wheels because the weight is not excessively large. The axle will spin freely inside a greased tube in the wheel center.

If the noise only happens during braking, a rotor probably has a very poor surface finish and needs to be resurfaced so as not to rapidly wear the brake pads. If the rotors are drilled or slotted, the noise is perfectly normal and can be ignored. If the noise occurs while driving along and gets louder at higher speed iit may be due to damaged wheel bearings. On some vehicles, removing a brake rotor requires…
You should change the wheels when they become worn out, you will notice that the silicone coating on top of the wheel is much thiner then it used to be. when it is no longer comfortable to ride, it's time to change the wheels. [depends on how often you ride, it may take a month or even a whole year before it's time to change your wheels..]
A spindle is a narrow shaft that is used for rotating parts that rotate around the spindle itself. Often the spindle is mounted fixed at one end, and open at the other so that parts can be easily installed without removing the spindle. A shaft is a rotating cylinder that may or may not have parts, such as wheels (turbine), impellers and oil slingers...etc. fixed to it. it is mounted most often at both ends…
