Possible Bent A-Arm and Tweaked Frame?

[Cable810]

Starting to do some maintenance of the ol girl. I noticed that the knuckle on the left side of the sled leans towards the back of the sled pretty good compared to the the other side. See the attached pictures. The skis are way outta wack as well. Left side sticks forward compared to the right side.

Forgive the bad photos i did my best to get the level as perfect as I could.

What does the shock spacing look like with the upper A-arm? G.B.

 

[Cable810]

Spacing as in?

 

[YukonMP]

The shock normally passes through the A arms with equal spacing front and back, top and bottom. Yours won't be. Once, when backing up I had a ski hang up on an obstacle and I bent/twisted the A arms ever so slightly. The result was a different lean/tilt on the spindles (you call knuckles) and one ski ahead of the other. I was able to just insert a 5 foot bar and gently tweak them back. That was over 12k kms ago and all is good.

If you are of another generation when I say tweak I mean bend back with controlled force.

Oh okay I'm new to working on sleds. I've grown up working on vehicles. I'll give that a check when I get home from work.

Anyone have a measurement so I have an idea where they are supposed to be at?

 

[YukonMP]

No measurement required because the space from A arm to shock is approximately equal front and back. It will all make sense when you have the sled in front of you. I can't help because my sled is an MP. I was in the same boat as you a few short years ago, the MP is only my second sled. Good luck.

Okay! I didn't notice anything bent on the left side other than the spindle. I noticed on the right side the tierod has a slight bend in it.

I'm assuming that the right spindle being straight up and down is how they are supposed to be.

I'm probably gonna take everything apart up front and compare parts to see if there is anything outta wack

 

[livewire_101proof]

Where the shock goes down through the a arm should be close to centered from front to back, guessing urs is not. Check all of your a arm bushings, may be contributing some, but not all of it. If a arms are not bent then u may have bent your frame up front right where the a arms mount, it is common on nytros and they are pretty similar frame so im guessing its common on these too. If it hit anything hard it will bend either an a arm or the frame and that will change that angle of ur spindle since one stays put and the other moves, that also moves the ski with it so one ski sticks out ahead of the other one. Should be alot of threads in a search with pics to show u what to look for. Good luck

So after a little research and looking at different photos I'm almost certain my frame is tweaked... Gonna pull the frame out and check it out.

Know anyone with the same sled to compare dimensions and eyeball to?

Sadly I don't know anyone around my area with the same sled. I found this thread and it is pretty much telling me that my frame is bent.https://ty4stroke.com/threads/bent-subframe-and.151746/

I'm pretty sure my shocks are center in the Upper and Lower A-Arms I'll double check that today.

The whole left side suspension is lose and the ball joint shot. Pretty sure the spindle hole where the ski botls through is womped out as well... gonna keep digging here and on the sled.

So I'm at the point to unbolt the frame and get it out!

Here are photos of the shocks.
Left side the knuckle is unbolted from the bottom a-arm

The right shock is not touching the upper arm as it appears in the photo. I did notice that the upper arm the tube that faces towards the back of the sled has a slight curve in it. That doesn't make sense cause I don't have reverse so how in the world did that wind up with a curve in it??

Right arm is bent. Look for paint cracks at the welds. Like said many of us have just bent them back but your choice.

 

[cannondale27]

If you put a straightedge on the right upper arm rear main tube you will see its not straight.

I'll buzz back into the garage and check!!
