Nuts & Bolts: Slingers

I’m upgrading to chromoly shafts on the Dana 44 in the front of my Chevy truck. I noticed that there’s a thin metal dust shield on the original stub shafts that isn’t on my new ones. Do I need these shields, and if so, where do I get them?

Yes, those dust shields are important and you need them. Those shields (sometimes called slingers) are what the inner wheel seal rides against, so they help keep water and grime out of the inner spindle and wheel bearings. You can sometimes knock the original shields off of the stock stub shafts and reuse them, but it’s hard to do that without damaging the shields, especially if some rust has set in. As far as we know, all Dana 44s and most Dana 30s with locking hubs used the same dust shield regardless of the vehicle. The Spicer part number for that shield is 36364, while Dana 60 dust shields are Spicer PN 37308. These shields run about $4.99 each depending on where you get them, but any Dana Spicer dealer should be able to get you what you need. We haven’t had much luck ordering them at our local big box auto parts stores, so plan ahead in case it takes a few days to get them.
