Yukon Gear & Axle Yoke For Gm 7.5" And 7.625" (Mech 3R) In A Triple Lip Design.
$134.89
Q:Does this accept the 1.188" bearing cap? Most yokes that claim to fit my 2001 RWD Chevy Astro are 1.125", which is not correct for my van. Show Less

A:BEST ANSWERHi JC, I'm happy to assist you. This item accepts 1.125 inches cap. As per checking, we don't have a driveshaft pinion yoke for the 2001 Chevrolet Astro that fits a 1.88 inches bearing cap. We suggest that you check your local auto parts store. For more maintenance parts, we have a sale on brake parts. To get one for your vehicle, click this link: https://www.carparts.com/search?q=brake I hope this helps. Enjoy shopping at Carparts.com! Show less
