So I've had a weird issue for a few years now where new brake pads/rotors make the truck drive super smooth at first, but over a short amount of time it seems like the rotors become "warped" and the steering wheel will wobble sometimes at higher speeds, or during a hard acceleration or during hard braking... I finally came to the conclusion that it was likely a wheel hub issue, so I decided to change both front wheel hubs and bearings.

The results are way more pronounced than I expected, and it's amazing how much better the truck tracks - when I steer I get much better "feel" and the wheel wants to return to center with quite a bit more force than before - it's nearly as noticeable as the newer vehicles with that power assisted roll-bar/stability package. I honestly can't believe the difference, and it makes me want to replace the rears as well.

Bearings and related nuts/bolts came from Rockauto (https://www.rockauto.com/en/moreinfo...&pt=1636&jsn=1), and new wheel hubs are factory, and came from ECS tuning (https://www.ecstuning.com/b-genuine-...b/95834160501/).

I watched a bunch of videos online, but most appear to be for the 955 and involve pressing the bearing in and out. I bought a bearing press/puller kit off eBay (https://www.ebay.com/itm/255323443690) and was ready to remove the entire wheel carrier if necessary - but once I went through the Porsche manual I realized it was much easier than I though. The most difficult part is the final torqueing of the bearing bolts since there is not a lot of room, but other than that it's way simple, and really only required one "special tool" in the form of a generic hub puller. The one I used came from Amazon ( ).

BTW, I have the official tools for supporting the calipers (seen in the image below) and they are absolutely worth every penny (https://porsche.snapon.com/special-t...temid=16580042).



All you really have to do is remove the axel nut, remove the brake caliper/rotor, loosen the bearings bolts, then use the hub puller to push the axel out of the hub. I have a shop press so I pre-pressed the new bearings and hubs, but that can be done by any shop, or with a bearing/hub tool like the one I got off eBay. Install is easier than removal.

I didn't really write-up a how-to, but I created a document with all the steps from the shop manual, as well as the related torque values, and it's attached below.
