I found this video very helpful. It makes me feel confidant that i could do it myself.

By all that's Holy, don't consider this anything like authoritative.

In fact, in most places, it's outright WRONG. The crush sleeve and pinion torque is one example... they misinterpreted the pinion nut torque. It's the rotation torque AFTER the pinion bearing has been preloaded. It takes at least 500 ft-lbs to crush the crush sleeve (not 5-9 ft-lbs as stated) and correctly preload the pinion bearings. When you get close to the right rotational torque, you gradually tighten the pinion nut until it's right. Getting that sleeve to crush is one of the hardest parts of the job and I've seen some of the biggest impact wrenches unable to do some and we used six-foot breaker bars.

As to the gear pattern, they didn't address ring gear position at all and barely talked about pinion depth. They didn't address carrier bearing preload at all and they pulled the carrier and didn't mark the shims side to side so they could be replaced, They barely talked about what a correct ring gear pattern is.

If they let that truck go the way it was, that diff blew three miles down the road. The host was clueless about diff work so I hope they had a backup guy that did the actual work off camera.

If you want to learn about diffs, here http://www.ringpinion.com/DiffBook.aspx is a diff book written for the home wrencher.

An R&P change is definitely within the skill set many shadetrees and hobby wrenchers have and I encourage people to go for it with the right instructions. This video ain't it. I could forgive a very brief outline of the process but not when it's dead WRONG on so many levels.

And how do I know this??? Look at the first name on the cover of that diff book.

 

Funny video....full of fails.....don't worry drive line shops....you'll still get my work....

 

R&P jobs are definitely one thing worth paying for. I've done probably 3 dozen R&P swaps in mustangs, but REALLY would like to see an DIY article for a R&P swap for the front IFS in the newer F150 trucks

 

Ford might have one @ Flat rate tech -

This one is good, you have to down load it at the site -

Diag. & Repair Rear Axle Whine

I've seen another out there, -can't locate it, yet.

 

o ok. Maybe i cant do it myself lol. I dont know anything about gears.

 

I think this is even better then that video.

Yeah, I knew hardly anything about rearends about a week ago. But after the little bit of research I've done in the pass week, I thought this video was way off! Dude just made a fool of himself IMO.

I think it would be hilarious if somebody made a funny edit of this video!

 

Nice , that's the other one. Couldn't recall where that was.

That's probably the best one out there.
