I just found this forum and it looks like there is a lot of good info here. I just got a 94 400 4x4 and when I get up to about 30 or 35 the front end starts to shake any Suggestions ?

 

if you are using flatproof in the front tires that could cause this problem

Also check to see if you have mud behind wheels or check steering arm or tie rods Cob

 

Is there a difference when in 4WD? Check the end of the steering stem where the tie-rods connect. Replacing the bushing at the end of the stem with HPD's bronze($30) would'nt hurt either. Also check the "toe" of the tires. OEM specs for my '99 call for them to be slightly out.

make sure there are no squirrels or chipmunks up in the suspension. They like Polaris too.

No, actually, check your tie rod ends--both inner and outer.

 

I can certainly testify to the tire sealer making one shake especially when the tires are cold seems all the sealer goes to the bottom of the tires when you park for a while then it takes a while for it to get spread back around evenly and balance the tires. Thank goodness I got these new mudrunners.

Thanks for the tips I found out this weekend that it has tire sealer in it and it has been just sitting for about 4 months I pulled the tires off my friends and put them on mine and no more shake I broke the bead on one of the tires and the tire sealer was all clumped up so I thinks this is a good excuse to get new tires.Has anyone used the new ITP Trail wolf tire yet?
