Notes:
Non-Knurled ball joints recommended for replacing non-knurled ball jointsDue to these ball joints being tight tolerance, metal on metal ball joints, proper fitment is critical. Using the wrong style of ball joints can cause significant steering issues. We always recommend installing non-knurled ball joints until non-knurled ball joints are no longer a press fit into the axle end forging bores. If your axle end forging bores have been enlarged to the point that non-knurled ball joints are no longer a press fit, knurled ball joints are required.
Use of the improper ball joint style for the axle housing voids our lifetime warranty. It is up to the installer to verify the proper ball joint style is being used.

Soft and warm
Color: Cream
This cashmere scarf is honestly light weight, soft and warm. My only complaint would be that the width measurement isn’t wide. Measures at 19.5 but stretches a bit. So I can’t really wrap it how i like. Despite that I love the scarf and I am keeping it. With a safety pin I’ll be able to wear it how I intend to.

Nice quality and great price
Color: Cream
This was purchased as a gift and I was a little concerned about the price for a cashmere scarf but it arrived beautifully packaged and very nice quality. My friend loves it and wears it often. The color was as advertised and perfect to wear with anything.

Versatile and warm
Size: One Size, Color: Grey Melange
The product was great in multiple settings, like hiking in a wintry mix in Michigan or walking down the cold, windy streets of Chicago. It’s better than my previous beanie, as the cashmere had more give than the more rigid one I had before, while retaining all the warmth
