Query: bad casters

I have had this shop vac less than 3 months and the front casters have broke. One of them has been totaly destroyed. It (the) shop vac has not been abused at all. The other day I noticed that the shop vac was moving poorly on my drive way. So I checked it out and found that one of the front casters was totaly broken. How do I GET new casters for this shop vac. model #LPV550/ 16gal, 5.5 hp. I went back to Lowes and bought a new set of casters but they did not fit. Please Help. thanx
