do I need 2, one for each side?

I used these in a Troy Bilt Lawn Tractor, on the main pulley that is used to vary the speed of the motor. In that application, you need TWO and they are sandwiched to each other.

There are two bearings, one on each side. You can test each bearing to see if they are both bad, but I would recommend just replacing them both while you're at it.

Works on either side. If replacing both, you'll need to order two. (Unless they've updated the listing to sell them in pairs.)

Even though it SAYS two, it only comes with one. I haven't tried to move it from side to side yet.

Hi. It's just meant for one on each end. 2 on each end would be cramped. Hope that helps.

Yes,you can use just one side, because there is a plate that you attach to the toilet, then the bars in each end. However,you may want both bars for stability.

Sorry for the late reply, 1 kit is for one side only. you will need 2 kits.

No. I needed only one when I ordered, but I bought two just in case they didn't match or lineup correctly. I was glad I did because they were not identical to the one I had and they did not lineup. The two I bought work just fine together.

It actually comes with 2. One for each side. They work awesomely! Hope this helps.

Yes an rca plug is needed one or two but doesn't matter which side if only one is used.

If you want one on each side yes. We purchased 1 and used that on a trip or two and then liked it so much went ahead and purchased one for the other side.

Only one...just like it says. So buy two if you need to replace both sides.

There are two, they are the same part number though. So it doesn't matter if which goes where. Just get a quantity of two only the positioning matters.

I'm not sure but I'm guessing you can order two. They are not left or right specific and are a great deal of support for the price.

Yes, you need 2 for the front- right and left is the same part. However for the rear, use part # 181925. You also need 2, right and left again are the same part. You can do both fronts OR both rears OR all four at the same time. DO NOT replace one side only. This will result in dangerous handling. ALWAYS replace in pairs- Left AND right.

No, you just need the one, if your just doing a headboard. If you want to attach a footboard you will need 2

I thought I would need two but one is good enough for me. I think it depends on how well you understand your car. What I mean is that, if you can feel when your tires touch something, then go with one. Otherwise, play it safe with two.

no it's just one. If you require both sides YES get a pair. But i only had one side that was out of control with a forced let down.
