My suitcase rolls very smoothly even in my garage which has a slightly sloped floor if I take my hand off the suitcase it starts to roll towards the garage door .
I was traveling with a group of friends and one of the remarked my suitcase was very quiet as we walk down the path .
The removal of the original wheels on my suitcase was difficult I had to use a Dremel it helps to have a cut off wheel on a Dremel that is at least an inch and a half in diameter to reach the original axle that came with your suitcase .
When cutting off your original axle were my protection and insulation protection .
Putting the wheels on was very easy all the tools you need come with the kit allen , wrench bolts and washers .
I used the washers as spacers to make sure the wheel did not touch the assembly and rub.
I have been traveling by air since 1964 the suitcase I have now is the best I ever had with the exception of the poor quality wheels that it came with from the factory .
Now I have what I believe to be the best suitcase ever after the installation of these wheels.
