TIMKENSP580310 Preset, Greased and Pre-Sealed

Don’t go cheap when it comes to wheel bearings off your truck , these seem solid and built well will see how they hold up compared to AC Delco

Hub and wiring matched my 2001 GMC Sierra 2500HD exactly!

Nice hubs for my 2005 Chevy 2500hd. Been on for 55k miles.

Most of what I want to say is already stated in other 5-star reviews. The unit is a perfect fit. It comes with a new wiring pigtail that even includes new plastic clips. I considered the cheaper knock-off brands, but I've had poor experiences with them in the past so I feel the extra money to get Timken quality is worth every penny. Installation was very straight forward. You will need a 36mm socket for the axle nut. Trust me, you can't make due with a giant Crescent Wrench. You can buy the socket from Amazon or go to <pick name of your favorite orange parts store> and use their free tool loaner service to borrow one. This part is exactly the same part you would get at your local parts store, but about $120 cheaper. Seems like an easy decision to me. A bit of advice for reassembly: be sure to clean the rust and crud off the old o-ring very carefully, give it a thin smear of grease, and then clean the mounting area that the o-ring sits in with some sandpaper or wire brush before reassembling the new hub with the old o-ring. Go ahead and give the whole mounting surface a thin smear of grease for easy assembly and corrosion prevention. I was a little surprised that the hub didn't come with a new o-ring, but the old one cleaned up nicely and it all went together easily. Also, clean up the threads of the bolts with a wire wheel before reassembly with blue thread locker compound. Finally, make sure that all the little plastic clips are firmly pressed into their respective mounting holes and the wire is plugged into the socket behind the shock mount.

Perfect fit as good as OEM

These wheel hubs were USA made, but not anymore! Just received the hub today 9-4-22 and after opening the box the label shows made in South Korea. I am completely disappointed after waiting 2 days I could've went to my local auto parts store and bought an overseas part for $50 less.

The TIMKEN SP580310 works for both 4x4 and 2x4 but this hub does not come with dust covers. I reused my old back dust cover from my old hub. I bent the back dust cover a bit when I removed the cover with a flat head screw driver and a hammer. I hammered the bent area back into shape.For the FRONT dust cover you can buy a Dorman - HELP 13920 Wheel Hub Dust Caps here on amazon.Note: This dust cover is made of a thin soft metal. DO NOT HAMMER the dust cover directly or you will dent (ask me how I know). Instead tap the dust cover along the edged using a flat head screw driver and a mallet or hammer. See pictures.

This item fit the 2004 Chevy Silverado 2500 extended cab 4 x 4 perfectly. The ABS sensor plugged right in and the clip that were included popped right in place. If they are off a little, they can be slid one way or the other.I gave it 4 stars because it could have included the bolts and seal. It was hard trying to find the bolts for the 2500. I found they are the same size.as the 1500(dorman 917-517). But there are only 3 in the pkg for the 1500. So, you need to order the extra pkg to get the last bolt. The bolts are common to alot of 3 hole hub car and trucks. I removed the old hub by loosening the 4 bolts half way and putting a bar between the frame and the bolt head. then I turned the wheel to use the power steering force to push the hub loose. I did this on both the front and rear side of the hub. Then tapped it out the rest of the way.Hope this helps.
