8.8" Equals 3 Teeth Max!

Recommended Posts

So trying to decide what to do, after being a daily driver, sitting is not good for her! If it would have had a 9" in her there would be a Canon 5D Mark3 in my camera bag and the Bronco in the driveway. I have to admit the 2017 F150 goes twice the distance, extremely quite (I heard a pine needle caught under the wiper slapping the windshield and the full on stereo is nice!

 

My plan had be to keep her after the insurance totaled it, I had just put on the new front hubs, after the wreck and the new springs right before she got hit? I'm wondering if the third tooth failed with the pinion bearing or were all 3missing until thx pinion issue? I didn't pull the cover when it popped the second hole, just JB welded it up, topped off the fluid and kept on going for over a year! And the first missing tooth had 2 years! Motorcycle's are my thing, can't even find a decent 3 legged unit. Hate to see her sitting and miss driving her! She did get me home from my concert shoot that night! But pushing 5 months now just sitting with my new tires too!

Hey RR....my thought would be a salvage yard rear and other pieces and make her a weekend driver.

Good luck whatever you choose.

ain't no shame in salvage yard parts. Always shame in not having fun in a Bronco.

Currie can build a custom rear axle for you that includes an 8.8 center, with 9" side tubes. This let's you upgrade to Disc brakes if you want or keep the old shoe setup. This also eliminates the C clip need for axle retention making a more solid axle. You also get 9" bearing on the outer ends and let me tell you it's one solid setup. Another bonus is it's still an 8.8 so no driveline or diff replacement but in your case it does sound like a new diff is in order.

I included the Bill and Laiding plus Dimensions Info for Currie and most of the info will apply to any axle builder.

 

You can always pull an axle from a junkyard however in my experience living in AZ, that really sucked. I pulled two to replace the axle that had a bearing leak. Both the pulled axles had the same leak on the same side (passenger i.e. tight turns). The AZ part sucked because both times I had to pull these in the middle of the summer so it's 118 out and likely 128 in the middle of the junkyard. Plus all that effort BOTH times for nothing. Still there are treasures including axles in those yards, and possibly better odds than Vegas :)

Purchase Cost (I added the Diff cover and hate it! however that cost is equal to the freight shipping with an extra $50 for lift gate)

Full build out info needed for Currie Which includes Disc Brake Conversion, plus Shock/Perch mount angles/offsets (Currie can weld these on for you but make sure you talk them through it.
