Grease is added to trailer tires and rims to roll on roads; this sort of lubrication allows friction-free movement around its axis.
Why is There Grease on My Trailer Rims? The presence of grease on trailer rims is due to improper maintenance, worn-out bearings, spindle rusting, and damaged caliper piston.
Sometimes this grease comes out of the seal and flows around the tire rims. Due to this problem, the wheels of the trailer no more allow friction-free movement.
Why is There Grease on My Trailer Rims?
The wheels of trailers have a specific structure supported by some essential elements. This seal further contains a unique type of bearing to roll the wheel without any hindrance.
For this, the bearing well lubricates by any readily available but well-standardized thick lubricant. This sort of lubrication avoids friction for smooth rolling of the vehicle on roads irrespective of surface type.
Low Thickness or Low Viscosity of Grease
Lubricants are always significantly more viscous than conventional petroleum products. For example, in wheels, relatively more viscous grease requires.
Sometimes, people ignore this feature and use less-viscous lubrication stuff in the bearings of the wheel. Therefore, pressure applies on wheels during payload while running on roads.
The grease or lubricant leaks from the seal and spread around the rims of your trailer. Hence, the purpose of lubrication dies out with this leakage.
Overheating inside the Wheel’s Casing or Seal
In addition to this, insufficient grease inside the seal results in friction. It happens when there is maximum pressure on the wheels of the vehicle.
Due to excessive excitation in molecular movement and their suppression, increasing pressure causes a temperature rise. This rise in temperature leads to a decrease in the viscosity of lubricant or grease.
A grease with less viscosity cannot sustain itself inside the seams of the wheels. Therefore, it comes out of the seams of the wheel and spreads around the rims of your trailer.
In other words, this leakage of grease indicates your faulty lubricant besides another malfunctioning.
Lack of Periodic and Regular Maintenance of trailer rims
The vehicle needs sufficient support in the form of its regular inspection and maintenance in advance if required. It may be due to diligence.
If you are going to ignore this very aspect of the smooth operation of your vehicle, then it will no more support you on your journey.
Most of the time, people keep operating their vehicles recklessly. Due to this, the seals of the wheels may worn out badly.
These worn-out seals, later on, result in leakage of grease and lubrication material inside bearings. Hence, this grease spreads around the rims of your vehicle.
Broken and Exploded Seals of trailer tires
Furthermore, seals of wheals damage or explode due to overloading and rough road surfaces where your vehicle runs.
It happens when the excessive load on the trailer exerts pressure beyond a certain threshold of the seam. In this, cracks appear in the seam, and leakage starts from it.
There are other reasons behind seal failure, including improper installation, poor maintenance, and improper bearing adjustment.
Therefore, to keep grease inside seals of wheels, you must have a proper and periodic maintenance schedule for your vehicle. In addition, these seals are tight enough to avoid any leakage of lubrication material.
You can resolve this problem by overcoming these failure factors and replace with a new well-reputed brand seal. While installing a new seal, you have to check the given specification of the manufacturer.
Utilization of Single Lip Seal
Lip seal is an essential component of your vehicle engine system because it keeps away the dirt and another contaminant out and retains the grease or lubricant material inside.
According to a survey, almost 65% to 75% of expert mechanics use this item. However, you must have considered some aspects when installed it, including caution, selection criteria, and installation method.
If you use a single lip, it may chance of grease leakage on the trailer rims from the back rather than at the front of the hub.
You can resolve this issue by replacing it with a double lip seal. It has a radial spring and contains two rubber lips that have a connection with the spindle.
This radial spring holds the spindle more tightly and minimizes the chance of leakage of grease and seal damage.
Sometimes the leakage problem of grease on the trailer comes from the front side of the rims occur due to bearing.
In addition, excessive heat exerts a negative impact on the like damage, worn out, or too much tightening.
This alteration can lead to thinning of grease or lubricant material. You can also check these symptoms by rotating or jacking up the bearing. In this case, the axial movement also becomes high.
You can resolve this issue by holding the tire from the top and bottom portion and pressing the bottom away while dragging the top toward your direction. It can lower the movement of the axial.
Correct adjustment of the bearing removes the too much tightening/loosening problem.
In this case, you have to use the proper dimension tools and specified procedures. In addition, you should avoid using the impact wrench.
You can also use bearing buddy bras and tighten the metal collar around it unless it becomes secure.
Too Much Greasing
Too much greasing consumption can ultimately put you in a big mistake that is costly for you to bear. Therefore, you should determine the amount of grease with proper calculation and its frequency.
This factor entirely depends on the bearing dimension. The damage produced by it is the worn-out seal, and operating temperature becomes high.
You can avoid this issue by considering some factors. It includes the right amount of greasing material and proper calculation and frequency.
You have to maintain the trailer hub condition regularly. In this case, remove the bearing by the hammer’s slight tapping.
Next, tap the base bottom and another side of the hub unless it becomes detached. Then pull the spindle by removing the tab lock or cotter key.
You have to inspect the spindle condition if any scratches or cracks appear and clean it with the emery cloth that removes the minor scratch.
If the situation of the spindle is worse, then you need to replace the axle. The appropriate technique to inspect grease by removing the spindle assembly.
Corrosion of Brake Caliper Piston
Using a brake caliper is a vital part of the trailer brake system, and the piston is essential for the brake caliper.
Failure of this part happens due to various reasons like rust, brake fluid contamination, and the damaged piston seal.
Therefore, you have to regularly examine the brake system of your trailer and the impaired brake caliper piston sign and symptoms.
You can replace it with a new caliper piston in few steps. First, detach the caliper, applying pressure to blow out the piston. Next, clean the caliper and erase the old seal and install a new assembly.
Leakage from Dust Cap
Leakage from the dust cap is not a big concern or issue for you. However, if you want to remove the dust cap, then replace it with the new one and ensure that you seal it properly.
If you overlook your trailer’s appropriate maintenance or leave it idle for an extended period, you may experience a leaking problem.
How Common is Grease Leakage at the Trailer Rims?
It depends on various factors like a vehicle carrying the load, Wheel size, regular maintenance.
In addition, water intrusion damages the seal during driving of the trailer, causing it to damage bearings, seal, and contaminate the grease.
You have to maintain it properly and change the lubricant material timely to avoid such consequences.
