Can not afford or just don't want to pay ?
Next there will be a mower repair shop somewhere near by that sells certified after market parts.
Rotary, Oregon , Stens & Prime Line all list those spindles for around 1/2 to 2/3 the Cub price.
These are certified spares ( usually from the same factory ) and only marginally more expensive than the Amazon sellers.
Then there are dozens of shops like Jacks, Messicks, Barrets , Small Engine Warehouse, Small Engine Suppliers ,etc etc, that are real, have real phone numbers , real customer support and a real physical presence.
If you are a ligit repairer with a tax number they all offer trade prices and even I get a trade discount from some of them.
And finally, unless one of the legs is broken there is no reason to replace the entire assembly as all the above suppliers flog rebuild kits.
The example I like to use is spindle bearings.
I charge $ 18 each for them and use Chinese bearing bought from my wholesaler.
A customer thought I was ripping him off cause he could buy the same 6203 & 6205 bearings off ebay for $ 5 a pair with free postage.
The fact that the numbers are a size and not a duty rating was beyond him .
I agreed to fit them if he acknowledged he supplied the bearings & I am absolved from warranty claim.
So he decided to fit them himself and save another "rip off" $40.
Needless to say the bearing failed in fairly short time when his daughter was mowing the grass with the I plugs in her ears so she did not hear or notice what was happening till she turned around and saw the mess on the grass, chopped up sprinklers and torn up lawn.
In the mean time the pulleys had chewed about 3/4 " off the top of the spindle housings , the blades had chewed through the deck and had even been smashing into each other.
A replacement deck was $ 200 ( used ) + $ 90 ( spindles ) + $ 90 ( blades ) + $ 85 ( belt ) + $15 ( springs ) + $120 ( labour ).
The bearing when removed were blue, with no sign of any grease in them. The 6205's had a plastic cage which had melted ( shopping trolley wheel bearings ) .
These bearings were listed on Ebay as fitting all Husqvarna 3 bolt and 4 bolt spindles, all Craftsman & McCulloch spindles.
HE complained to Ebay( who did nothing ) & Paypal ( who refunded the $ 10 ).
He tried to put negative feed back onto the seller but it was too late.
The seller had a 99,9 feedback rating.
