Default Re: Wheel wobble

Thanks for the replies! After reading your repplies I jacked up the rear and hit the gas and watched it spin and it does not look like the break drum is sitting flush. In some spots the gap is tight and other spots it seems twice the size. I pulled the wheel off 4 different times to get it seated and I cant get it to seat correctly. Maybe this is the issue. What can I do to get it to seat correctly? If I have to replace the break drum is it just the drum itself or other break components that I need to remove. Thanks again for your help. I think you guys might be on the right track.

See my post on page 1 of this thread. It is what I did to correct my problem. I can't say that yours is exactly the same but the machinist/golf cart repair guy told me that he has bought NEW brake drums and found them to be imperfect and had to mill them to true them up.

So you have determined that the drum is not sitting flush on the axle, now you need to determine why before you buy anything.
If the drum is bad a new one will fix it but if the axle is the culprit a new drum will wobble also.
Remove the tire, remove the drum and see if something is between the axle face and drum, (maybe a rock or brake part?) Try to reinstall it checking the center ring.
You didn't mention when the issue actually started, after any type of work was done?

I bought the cart 4 years ago and immediately put a jakes 6" lift 12" wheels and 23" tires, clutch spring. I never drove it without those mods so I am not sure how it drove before those changes. I have very little experience working on these so I really don't know exactly what I am looking at but when I jack up the back of the cart and spin the wheels you can see that the area where the break drum comes up against the back plate or whatever you call the piece that holds the pads etc, it does not have an even gap. I had the wheel and drum off a bunch yesterday and did not see anything stuck in there. I will check again bu I am pretty sure there is nothing stuck in there. Please explain something to me... the hub mounts to the axle and the wheel mounts to the hub. The break drum simply sits between the wheel and the hub. If it were warped I should be able to tell by installing the wheel on the hub without the drum correct? Thanks again!

Yepper, After I finished reading I was going to suggest pulling the wheel and drum again, start the cart and watch the axle flange and see if it wobbles.
If it does you have a bent axle. If it doesn't wobble slide the drum back on the axle studs and see if it will seat flush. If it doesn't try pulling it off and rotating it 90 degrees to the next stud and try it again, do them all just to see if it will go on.
Check to see if the center ring is holding the drum out.

OK so I finally got some time to dig back into this and I need some more help. If I play with the drum enough I can get it to seat equally onto the hub. That is until I torque the lug nuts. As soon as I torque the lug nuts down one part of the drum pushes back further then the other and will not budge. I tried every different way of doing this (Tire in the air, tire on the ground, hand tighten them all and then tighten, etc. etc) and as soon as I torque the one side pushes in further. Any ideas of how to stop this? The way I can tell this by the way is the size of the gap/space between the drum and the back plate (Not sure of it's technical term) but the plate that holds the break components. In some spots it is very small and others up to 1/2-3/4" but again only after torquing the lugs down. Just a reminder this is a 97 G16 and I put a new axle and a new hub on thinking it would solve this and it has not. This was prior to be noticing the drum space. Thanks!

I am not up on this cart, but have we measured the center hole on the rim to the
centering rib on the hub, is the hub maybe a little to big and the rims are rocking
on it. If so the new hub needs a touch up.

Dooms, and Crash, I believe i mentioned that in post 8. Also, if its been driven 4 yrs. like this, the drum is likely to be no good,(parking brake being used like that!!)

And on a side note, brake shoes probably need to be changed as well.

Sorry guys. Just got a chance to take some pics. Let me know if you need other angles. This is after taking off a torqued down wheel. When I put the drum on just by hand it seems even.
