EZGO Electric Golf Cart Squeaks When I Let Off the Throttle

[HoosierHogg]

My EZGO electric cart squeals or squeaks when I let off the throttle and it gets louder when I go down a hill. It's not noticeable when I'm accelerating. Any ideas?

First time on a forum? Let’s start with year and model if cart, and whether it’s a Series, Sepex, or AC drive system.

Yes it is my first time. I think it's a 2005 EZ-GO TXT. Can't answer the rest.

I would say it's either a bad output shaft bearing or a bad bearing in the motor. Loose castle nuts on the rear brake drum/hub can also cause a squeak when coasting. Welcome to the forum.

I just put a new rear axle and rear hubs on it. Plus replaced all the bushings. I'm not much of a mechanic but I'll try to figure it out.

Did it squeak before you replaced the axle and hubs? How tight did you tighten the hub nuts?

Some people report that a PDS car will squeal while decelerating. Is the FNR switch on the dash or under the seat?

Yes it did squeak before. I'm not sure how tight the hub nuts are. My son did it while I was at work.

I have no idea what that means.

Where is the forward and reverse switch, on the dash or by your leg?

 

[HoosierHogg]

By my leg

Okay then it's a series system not a PDS. I'd check the hub nuts just to rule them out. The torque spec is 90 ft lbs then tighten more if needed to get the cotter key in. If that's not the problem I'd say it's either a bad output shaft bearing or motor bearing. You have to pull the motor to fix either so check the motor brushes while the motor in off the golf cart.

Ok thanks. My son is the mechanic in the family so I'll have him take a look.

Let us know what he finds. Good luck.
