When you watch the wheel spin you can see the run out.

Let me try this again. Is the wheel loose on the bearing, or is the wheel itself warped?

the wheel is not loose on the bearing so it must be warped I am guessing there is no easy fix for that.

Are the bearings good? If they are at all ” gritty” feeling or you can hear them they may be bad. A bad bearing can fail and still spin freely. This is where I would start it’s a cheap fix if that is the problem. I can’t really think of how a wheel would warp, but I’m sure anything is possible.

If you grab the wheel (facing it head on) and wiggle it is there any play side to side?

tried to look at the bearings but the wheel won’t come off. Is it pressed on the shaft? I can see a key on the shaft, I don’t want to beat on the wheel and make it worse than it is.

The wheel is a slip fit. If it appears stuck, give it a few taps with a rubber mallet or 2×4 and it should pop off. You can also give the shaft a tap or two from the front to loosen it up. The rear bearing is a slip fit and will (should) easily back out when you do. Front bearing is a press fit and will need to be driven out from behind with a wood dowel or something similar. Also, some ‘wobble’ on the wheel is acceptable and in most cases will not cause any problems. You should only be concerned about it if you see some really noticeable front/back motion of the blade when running the saw. Have you tried running it as is to see how it performs?

When did it start wobbling? To keep the wheel true, it should be mounted securely on a trued shaft. Guessing this might be also a bearing issue. Check this blog . The guy had a problem with the lower wheel, he explained how he fix the problem step by step.

tried tapping the wheel went as far as giving it a few good whacks wouldn’t budge. I don’t want to beat on it too much.

Squirt some PB blaster in there and let it sit and work it’s way in.
I’d lay the saw on its back personally in order for the stuff
to go with gravity. Also, with the weight on the ground,
you can pull up on the wheel to get it off.

I suppose the shaft could be bent.

You’re not talking about a lumpy tire, right?

Try to tap the wheels and look at the bearings. I think the problem is in bearings, which is making the wheels to wobble.

I just replaced the wheel shaft on my GO555 and it would not come out with tapping nor with hammering. I used a gear puller and pushed it out. It was a long hard push! The new one went in with a few light taps from a plastic mallet and some WD-40. The bearings were fine but the shaft was worn badly where ti bearing sat, causing a thump thump as the saw ran.
