Some experienced steering gear pre-lubricate the rims and mating surfaces of the hubs with the so-called thermal paste. Like, its benefits are much greater than from traditional means.
It’s no secret that hubs rust over time, which can cause a lot of problems. Let’s say that the wheel will “stick” tightly to this hub, and it will have to be disassembled with a sledgehammer, which is fraught with damage to expensive castings.
Knowing this, many drivers remove rust in advance with a special brush with a metal “nap” or lubricate the surfaces with copper or aluminum grease. These are all traditional methods that are often described. There is also a completely old-fashioned one, which our portal also talked about. There, instead of a lubricant, they use a simple pencil.
However, especially advanced citizens use thermal paste in the maintenance of their “iron horse”. This may only seem strange at first glance. The fact is that the brake discs get very hot during some heavy decelerations. To do this, they provide cooling channels. However, they are not always sufficient.
Heat is transferred both to the hub assembly itself and to the bearing of this hub. The lubricant in it is not always designed for extremely high temperatures, and it can also be simply old, partially lost its properties. Therefore, the lubricant flows out or dries out, causing a malfunction. Bearings are expensive. Yes, and on some models it is changed along with the hub assembly, which costs a pretty penny.
Thermal paste will help solve the problem. It dissipates heat faster, extending component life. Incidentally, the mating surfaces of aluminum rims can also be machined, as this metal has good thermal conductivity. And the wheels will be easier to remove.
An experiment was conducted on the Internet. On a regular passenger car, they accelerated to 80 km / h and braked to the ground. After just 5 delays, the discs had warmed up to almost 200 degrees! The temperature of the hub was almost 100 degrees at the same time! And after processing with thermal paste, the indicator dropped to 85 degrees. So there is a positive effect.
