Question Front End alignment

What do you pay for a front end alignment? I'm confident that I could do it but I don't know how and don't want to screw things up.

Re: Front End alignment

Simple, steering wheel straight, measure the distance in front/rear of front tires and adjust tie-rods to obtain ~1/4" toe-in.

As RZR Joe said. All u need is a tape measure and 10 mins of time. Do make sure the suspension is settled by driving the machine forward and backwards a few times B4 u set it.

Re: Front End alignment

I get about 15-20 in front of the thing and look at the front tires and see if they line up with the rear tires after you have the steering wheel straight. You will find that most of the time one side will be pointed in or out and you will have to adjust to get it in line with the rear tire. I do when I am not able to get a tape measure to go though the frame sometimes. You will find that alot of the machines are out of alignment from the factory on both atv's and sxs's.

Re: Front End alignment

I use string around jack stands and pull measurements off the frame to get the string lines spot on. Works great and alignment is exact.

Re: Front End alignment

So this is my setup. How can I adjust that without disassembling something?

Re: Front End alignment

Loosen the jamb nut and turn the tie-rod, it has a pivot inside the boot on the steering rack.

Re: Front End alignment

look just past the jam nut you will see slot on the rod about 2-3 in up, that is there so that a wrench will fit in to turn the rod to bring the wheel in or out to fix the alignment.

Re: Front End alignment

I adjust mine 1/8" toe out, I believe Polaris recommends 1/8" to 1/4" toe out.

Re: Front End alignment

In theory this is easy but in practice not so much. It is difficult to get precise measurements from consistent measurement points. Way more than 10 minutes. Remember we are aiming for two measurements from nobby tires being accurate to 1/8”. I would be glad if people would share exactly how they measure.

Re: Front End alignment

just butt the end of the tape measure body against the inner sidewall and pull the tape end to the other side. do the same front and back.

Yes. But needs to be measured from exactly the same point on the tire both sides and front and back. And this needs to be at very near the full diameter of the tire for the 1/8-1/4 toe out recommendation to have any meaning.

Joe, why toe in?
Is that what you would recommend for high speed desert runs?

Spending money I don't have on things I don't need to impress people I don't know.

Re: Front End alignment

The service manual actually calls for 1/8" toe-out if I remember correctly. Toe-out helps in corning but also causes the frontend to wander and it can also cause excessive CV angle on the inside tire (direction of turn). Slight toe-in will help the front end track better and the wheels will not fight one another and is typical of most vehicles. Toe-out can also cause oversteer which is useful in drifting to help break the rearend loose. As far as high speed desert stuff I have no idea, I would consult one of the race teams for their opinion. As an old school drag racer I'm use to going fast in straight line LOL

Re: Front End alignment

The reason for toe out is for keeping the vehicle going straight at speed through rough terrain, jumping, or whoops. I usually use 1/8-3/16" toe out front and rear. The easiest way I know is to wrap a string around the vehicle's tires (all 4) near the center line. This method is not totally accurate, but you will get close and it's free. If you have rear adjustable radius rods it really helps to fix the steering from pulling one way or the other. Note: front and rear wheels must be the same width (example 64" front and 64" rear).
