The rear suspension on your golf cart is everything if you are going to use it in aftermarket applications. The first thing anyone wants to add is a back seat or a cargo box, then a lift kit or an extended top. The list goes on and on. Then you realize that all that extra weight will need more support, so you throw a set of heavy-duty rear springs on it. Hopefully, you noticed that the E-Z-GO Gas ISO Mount Bushing was worn slap out while you were under there. If you didn't, you more than likely took note of the reduced ride quality. Either way, you are on the right track to getting the problem fixed. Make sure you look at the leaf spring bushings while you are under there. They wear much quicker.This golf cart bushing is located near the rear axle. You do not need any special tools to change it. All you might need is a set of sockets, a jack, and a few jack stands. All of that in hand, all that's left is to call Buggies Unlimited and order your E-Z-GO parts.
