It sounds like you may have blown a grease seal on the hub of your dolly.

Replacing the seal would not be too hard, but we first would need to determine what seal you would need. To do that you will need to pull the hub and measure the inner diameter of the hub where the seal installs and then measure the outer diameter of the spindle where the seal rides. You will want to use a digital or dial caliper to take this measurement.

Once you know what you have follow the link I attached and select your inner and outer dimensions from the filters and the correct seals will be listed.
