2018 850SP. 2" lift. New GP bushings all around. Horrible wobble begins at 40ish. Stops when not going straight.

I have these on my other machine, zero issues. Also used Tire Ject in other machine.

What have you checked? Alignment / camber/caster / tie rod ends / steering linkage from the handlebars to the power steering spline / etc. . You may even need to go as far as getting the wheels balanced. No common on ATV's but when you are at a loss in a situation like that it is another rabbit hole last ditch effort option.

Used to get that on my 06 dodge mega cab. Scary stuff

if you lifted it ,, defiantly needs toe set

Toe was insanely off. My friend eye balled it when he did the tie rods (before I bought it). Front of the tire measured 41". Rear measured 44". I believe I'm currently at 1/4" difference now.

I would've updated the post faster if I didn't get a phone call.

All good. Just trying to give you pointers on what to possibly look for. You may have already looked at most of those items but I wasn't sure.

 

[Polaris754]

you really need to run a plum line from the rear tires to do it right

What you describe is usually the tires. Many ATV tires, depending on brand, are notorious for being severely out of round and/or out or out of balance. Get them professionally balanced. Front AND rear. May not take away all the shimmy but it will significantly reduce it.

DO NOT LISTEN TO THESE GUYS!!!! Your problem is from going straight!!! Simple fix, DON'T GO STRAIGHT!!! All this means is you should be weaving and bobbing and drifting....

There, problem solved!!!!!!

Thanks. Some of those things I wouldn't have considered. The death wobble is gone, even when going straight! I hit 66.. small inconsistent shaking at random speeds, so I might go for a wheel balance, too.

The guy before me had it for a week. I didn't ride it before taking it apart to address the one way bearing. That's when I changed all bushings, etc. The problematic steering coupler is brand new, and I also cross drilled and bolted it to the shaft. The front end is tighter than a frog's asshole, so I don't know if that causes too much feedback which allows one to feel EVERYTHING.

Yes, it’s true Polaris power steering is a little too powerful at higher speeds, I finally got used to it.
