Hmm well I would start by checking the lengths of all the radius bars. Are they the same from side to side? Then if your able to. Pull both trailing arms off the bike and lay them side by side on the ground and see if they look remotely the same. Being as far out as you say it is. once you compare them sxs it will be obvious where the bend is. If that doesn't work then I would check the hubs and the spindles.

Is there a particular reason why you have a red trailing arm on the passenger side and a black one on the drivers side. Just looking at your pictures side by side. The arms themselves don't look the same.

I agree, theres not much back there, two radius arms, a trailing arm and a hub.
time to start doing a side by side comparison.
One thing did cross my mind, what if the hub is machined wrong ??
If the hub is defective that could explain it.

 

[shoubadaba]

your right hub is bent. In the pic it looks like its bent towards the back compared to the other side

 

[shoubadaba]

you sure the uper bolt that holds the radius rod to the hub isnt bent?

Right rear hub would be my guess, look at the comparison of each pic,
on the left the upper part of the hub is parallel with the 2x4,
the right side it looks like the upper part is not parallel with the 2x4.
The wood is toed out.
Of course its tough for us because were not there, however that hub looks suspect.

This is the question.

 

[Travz]

The hub, bearing, radius rods, and trailing arm have all been REPLACED WITH NEW and didn't help the issue.

 

[Travz]

I also ruled out the hub assembly by taking it off and clamping a board/string line to the flat part of the trailing arm with the same results. The red trailing arm is a new one that I borrowed from a friend to check if mine was bent.

 

[Terso01]

I don't know what to tell u then. I still think its the trailing arm. Being out 3.5"s should make it super easy to be able to see the problem.

But i have to ask how do u know it is 3.5"? What are you measuring from/to to get that measurement? If it was mine i would measure from the trailing arm mount point under the machine on the driverside to a point somwhere near the back of the passenger side trailing arm (just pick a point on the arm that is the same on both sides). Then repeat that from the passenger side trailing arm mount point to the same spot on the driver side trailing arm. Making an x under the machine so to speak. And see what those measurements are.

I say just start picking main points on the frame and measure to points on the rear suspension all over the place. Eventually something will jump out at you.

But don't compare the rear tow in/out to the front suspension at all.

Does the wheelbase measure the same from side to side?

 

[Travz]

I have measured myself in the ground. Lol. Every thing comes up correct. It's at the dealer now and they pulled a trailer arm off a new rzr and it didn't help. They can't find a thing bent either. I guess they are going to talk to Polaris about it Monday. To get that 3.5 inch measurement I was running a string line true with the rear wheel/tire to the front. The passager/bent side was 3.5" off of the back of the front tire. And was also not running true with the bottom frame rail where the driver/good side was. I've always used the string line method to set the tow on rzr's. I got the ideal from utube a few years ago from a atv alignment video.

 

[Travz]

Center to center the wheel base measures within a 1/8" from driver to passenger side. This was one of my first measurements

That is strange, for sure. It will be interesting to find out whats causing the problem.

 

[Southernblood77]

Travz did you ever find the problem? I am having the same issue!

 

[G8RZR]

Bump.
Similar problem here but I did come around a corner hot and hit a dirt shoulder dead center of right rear tire. Tire clearly toed out after that. New trailing arms on order from a member here. I thought that a bent trailing arm was the only way to explain what I am seeing. Now I am skeptical at best!
There was evidence of cracked powder coat and possibly a broken weld or two on mine so I assumed the arm is bent.
Should the plane where the hub assy bolts to the rear of the trailing arm be parallel to the line of the arm at the spherical bearing where it attaches to the frame? Or should I say, should the plane of the hub assy be perpendicular to the bolt that attaches the arm to the frame thru the spherical bearing?

 

[onemooretime]

Agreed. Bent frame?

No, bent trailing arms. Mine were bent between the shock mount and were they attached to the frame. Take a straight edge and lay it up against the inside opposite the tire mount side to check. I bought used one off the site and reinforced them like this...


Of course it looked a lot better when I first put them on...

 

[G8RZR]

onemoretime,
did the straight edge check and sho-nuff, almost 1/2" out at the rear hole for the sliders. I'm thinking some tree kickers might have helped in this situation.
OEM stuff seems a bit fragile to me.
Mine were bent between the shock mount and the rear hub.

Sorry, I havnt been on here in a while. The rear trailing arm mount was welded on out of tolerance. Which played out in my favor. Polaris stepped up and made it right by tremendously helping me with the trade in towards a new 1000xp. Which did take several emails and a phone call a day from me to the Polaris hotline. Maybe they got tiered of me calling lol. Needless to say never give up!!!

Nice, how crazy.
