5 Common 2008 Polaris RZR 800 problems

  1. Dust clogs Air Filter
  2. Pinion Nut Problem at the Rear side
  3. Power Steering Fluctuates while driving
  4. Transmission causes  Gear in reverse direction
  5. Brake Calipers are Dysfunctional

1.   Dust clogs Air Filter

The air filter of the Polaris RZR 800 is stealthy. But a serious issue came to the notice of users. The issue was that the air filter is getting packed with dust. The air filter allows much of the air to enter but eats up more dust.

It means the model comes with a faulty air filter.

Due to this, when the rear wheels keep rolling, the flow of air gets distributed in an unmonitored way. This affects the upper end of the engine. Air filters can easily disrupt the engine and its normal functioning.

It will overheat itself as well. The clogging of the air filter is a small issue in size. But there have been many incidents when the drivers complained about its impact on the healthy engines. But this issue has a viable solution. You won’t be needing any kind of technical help for this. But if you have no idea about it then professional accommodation would be suitable.

It is better to try to protect the Polaris engine. You would want to use a reliable engine kit with all the important tools.


Let’s discuss the replacement process for the air filter:

  • Exclude the cap or lid of the old air filter.
  • Also, eliminate the Cam-AM air filter.
  • Completely clean the air filter. Use soft fabric and brushes from the toolkit for thorough cleaning.
  • Position the OEM air filter in place of the old air filter with care.
  • Also, place the new cap on the air filter as the final step.

2.   Pinion Nut Problem at the Rear side

Another typical issue that comes with RZR 800. One sole reason behind this problem is the nylon or ‘nylock’ nut. This is not a reliable option at all. Metallic nuts are more reliable than nylon nuts.

Nylon nuts can be easily damaged. These dislocate themselves due to frequent driving. The nut leaves the bolt and causes more problems. This is not a glad tiding for you!

A discussion from Mowerify says that the differential grenades of your ride will take about $500-$1000 for repairing. The best solution is to rely on metal nuts. Also, if you are already driving with nylon nuts then shift to metal ones as soon as possible.

In this case ‘Pinion Nuts’ are a suitable option. So that you can save on this problem before it’s too late!

3.   Power Steering Fluctuates while driving

The steering cannot keep itself in one place! Might seem a small issue unless it withdraws a big chunk of money from your pocket for the repair. The power steering and its issues are also on this list. It is due to low voltage generation. Voltage below average will fluctuate the steering. Causing it to move in different directions. This issue also occurs when the drivers will step on the accelerator and brake at once.

In this case, a switch will act as a regulator. It will cut the power generation for the steering. So that the steering can reset itself. It will stop moving in different directions. Some owners don’t rely on a dedicated switch to cope with this annoying problem. So if you are from those then using a switch will be an effective solution.

This has been a fruitful explanation for the owners of Polaris RZR 800. Using a switch will increase the life length of the steering. So that you can enjoy your ride in the long run.

There are two more problems to go, let’s have a look at them down below!

4.   Transmission causes  Gear in reverse direction

Sometimes the gear will protrude in the reverse direction due to transmission. It is a serious problem with your ATV. In this case, the gear goes reverse due to the extra acceleration or gas. The transmission can get influenced in a negative way. It is better to detect the early symptoms of faulty transmission. So that you would be able to address this problem with the least repair cost.

But how?

In case when you put your Polaris RZR 800 on the throttle, it will produce a jarring acceleration. Also, the ATV produces a weird noise. Another symptom is that the RZR 800 will show poor performance in gear-based operations. All these symptoms show that there is something fishy with the transmission.

Now that you are well aware of the transmission problem. You also know about the symptoms to detect this issue earlier. There have been cases when the owners did not know about faulty transmission. It led them to incur a big loss later!

5.   Brake Calipers are Dysfunctional

The brake calipers are not working! Another issue reported by the owners. Polaris RZR 800 sometimes acts up due to defective brake calipers. These relate to the pads of the brake.

The brake stops the wheel and it does not move. The opposite occurs when this issue arises. Sometimes the pads of the brake will get damaged. The wheel becomes difficult to handle.

The steering shows fluctuations in voluntary spinning. The pistons become large in size. Their length also increases. The calipers of the brake will be clashing as well. The tires won’t be left behind to dodge the damage. The tires become flat. The wheels of your ATV will seem to be dispositioned from their places as well.

All these symptoms indicate that brake calipers are undergoing abrasion. Another big issue is that the wheel will drag itself as the driver handles it. In case when brake calipers are faulty, it is better to seek mechanical assistance.

Besides all the above-mentioned common Polaris RZR 800 problems, users report that there are clutch problems as well.

There’s nothing to worry about the defective clutch! Just pick up a good greasing oil and apply it on the clutch and all the components. The clutch becomes free and loses all the friction.

Yes, it’s true. The engine performance of the Polaris RZR 800 is phenomenal. It is a reliable engine. Serves well with its average fuel economy. The ATV provides a good mileage of about 1000-5000 miles on a single charge.
