Polaris RZRs are undoubtedly a blast to drive around. Whether on rocky terrain or in the sand, there’s just something about these four-wheelers that make you want to take on any challenge. They are some of the most powerful machines on wheels, meaning that if you want to go fast, you can do so safely and in style. Having them checked regularly is crucial to keep them safe and in working order. In this article, we will go over the 10 Polaris RZR parts that need to be regularly checked for your safety:
1. Throttle Cable
The throttle cable is the linkage that connects you to the gas pedal. It can be hard to replace since it often dangles from the dash, which means you have access everywhere in the vehicle, whether on an inlet hose, brake line, rocker’s arm, etc. In addition, the cable is most likely worn out or corroded, which can cause dangerous wear and tear at high speeds.
2. Transmission Oil Cooler
This part is located on the backside of your Polaris RZR, where it connects with the radiator core to keep your transmission from overheating when you are going fast. It is an essential part that must be regularly checked and replaced in case of leaks or damage.
3. Battery Cables
The battery cables are an easy fix if they are frayed or damaged. However, if not regularly checked, they can cause fire hazards to your internal components, be it the starter, fuel pump, or alternator. They can also wear out quickly, especially when your battery is getting old.
4. Rear Differential
A rear differential is a part that allows you to drive your Polaris RZR in both directions on the same axle. It can help you get maximum traction when going downhill, and it also enables you to maintain control when rounding corners. Unfortunately, most rear diffs on a Polaris RZR are bolted to the frame and do not have a limited slip feature. Therefore, you will need to check them frequently to prevent issues with your Polaris RZR.
5. Drive Shaft
The drive shaft is connected from the differential to your Polaris RZR’s transmission and has a slipper clutch. This device works to keep your Polaris RZR from locking up if the going gets tough. If you notice that the drive shaft has any fractures or cracks, you will want to replace it immediately.
6. Rocker Arm
Rocker’s arms are connected to your Polaris RZR on both sides and help keep the vehicle’s wheels from spinning when cornering hard. These are usually made from bronze which helps keep the part from corroding, rusting, or wearing out.
Upper and lower control arms connect your axle to the vehicle’s frame. They help keep your Polaris RZR going in a straight line when on uneven terrain, and they also help it turn when going around corners. However, a-arms can become worn out at high speeds because of the stress that they are put under from the steering rack, and it’s recommended that you regularly check these parts.
8. Rack and Pinion
The rack and pinion is the device that connects your front wheels to your Polaris RZR’s transfer case. It is essential because it helps the front suspension work correctly and helps the vehicle steer by using the steering wheel. However, this part can quickly become worn out due to rough terrain, traction control, or evil alignments.
The caster is the angle of your Polaris RZR’s steering axis and can be adjusted depending on how you want to drive. The caster helps keep your vehicle from pulling to either side when going around corners and helps your front wheels from getting stuck in the mud or snow. If you notice any damages with this part, you will need to replace it as soon as possible.
The reservoir is located on the top of your Polaris RZR and contains the oil that keeps your transmission and engine lubricated. This part is relatively hard to see, so it is a good idea to check it for leaks or damage.
The Bottom Line
For those wishing to check these parts regularly, the best way to do so is by going to a mechanic that specializes in Polaris RZRs. These vehicles require attention and regular maintenance to keep them running safely. That is why it is crucial for you to regularly check the parts that can become worn down, damaged, or corrupted.
