Full Version: Rear suspension

Hey guys I have a buddy who has a 06 Fusion 600. When he sits on it the suspension goes all the way down until it hits the rear blocks ( He's not a big guy) then when he gets back off it does not raise back up. We just had the rear shock rebuilt and still no difference. We have changed the settings on the springs all the way to stiff and it doesnt rebound the suspension back to its up position. Any help would be great Thanks

The shock absorber has nothing to do with ride height. Check your springs to see if they are broken or not secured on the short side of the spring mount. Your problem lies in the springs not the shock.

When we had the skid out we checked the springs over and did not see any cracks or breaks and they are secure in the correct holders. The only thing I can think of are maybe those springs have worn out. Only having 2yrs of riding and 1700 miles on them is that possible?

I would have to agree with bigfuse something wrong with the springs, either they are broke or not properly installed.

Can you pick the rear of the sled off the ground and set it on something using the bumper, then go and see if there is any load on the long arm of the spring that sets on the block behind idler wheels. Should take quite a bit of effort to lift arm up and over the idler to unload spring.

As far as your springs being wore out, would have to say not possible because you say it doesn't even return with no one on the sled. To act like this they have to be broke or installed wrong.

After you set on sled and get off sled and it stays colapsed if you pick on rear bumper goes it then return to where it should be? If you have to force it back then I would say something is binding.

Where are you located in rochester?

We did pull the springs and to me it didnt seem like there was that much tension on them I was expecting more. How many other ways would there be to install them wrong it looks like one way on and thats it. I'm guessing they have to broke somewhere then although we did not see any cracks at all.

Yes when we push the rear bumper down it compresses all the way to the blocks but does not rebound unless we pick up on the bumper. There does not feel like anything is binding and it move smoothly just no rebound.

I have seen in the past when the rear skid was taken out, the springs actually slid out towards the outside on the top section where the coils are and ended up not in the groove of the upper wheel, but resting on the collar section. this resulted in a very similar behaviour to what you are describing. Again I am talking the top, not where you make the adjustments. Hope this helps.

Never seen 2 springs break at once, and certainly never after that short of time/miles.

Some rear skid springs are to soft,to hard or are faulty right from factory.My Dragon had bad rear skid springs right from the start,the shock is fine.My Dealer replaced them under warranty and it's fine now.

Polaris softened the rear skid springs because of all the complaints from the Pro X series models being to stiff.

Your dealer will check the shock first as a precoshonary measure than go to the rear skid springs and replace them.

Thanks guys I'll take a look at the top part where the coil rests and make sure its in its correct spot. If all else fails I guess its a call to the dealer.

Mr. Obvious here. You don't have anything under that sled do you? Like a set of dollies? Happens all the time, will result in exact problem you describe. Didn't see it mentioned anywhere above, thought it should be considered. Problem results in no support under front of skid, so it can't help hold the back end up. You should check that front skid shock/spring out also. It's just as likely the culprit as something going on in the rear.

Lifting the springs off the perches at the end of the long arm is not that tough. Wild guess - something like 35-50 lbs.?

Never thought of that but very good point had that happen to me before.
