Look up the part number for your complete spindle assembly, then go see your local husqvarna/poulan or MTD dealer to order the part. Sears has a bad habit of making up prices for items them are available for less money through the dealer. Good example is the cooling fan on top of the hydrogear transmission sears wants like close to $50 for a part that hydrogear retails for $7.95
Just looked up a part the other day for $1.37 that sears wants $4.95
