Got a weird request for my little side gig doing gears. 1992 E250 4x4 van that I think is a Quigley conversion. Low pinion driver drop Dana 44 on leaf springs. 460 E4OD Dana 60 rear. Have the complete axles only in my garage. The van is getting a body off frame restoration, currently down to a bare frame.

I haven’t done a low pinion front axle in a long time. So thought I’d document my chess moves for fun and let the board critique my progress. I removed 3.55 gears and am installing 3.73’s in their place. (I know… I know… don’t shoot the messenger). Remember, it drives on the coast side, and coasts on the drive side. Leaving front open carrier.

First test. .000 pinion shims .055 on the ring gear side of the carrier, .050 on the pinion side of the carrier. Had about .025 of backlash.

Good place to mention that I have setup bearings so I can take apart and put together without pullers. Have mountains of shims from years of doing gear installs.

Second setup. .010 in on pinion. 0.040 on RG side .065 on pinion side. .011 backlash. Still not deep enough but coming in.

.024 under the pinion. .030 on the RG side. .075 on the pinion side. .009 backlash.

Last setup for the night. .030 under the pinion. .025 on the RG side. .080 on the pinion side. .011 backlash. Starting to go the wrong direction inwards on the cost contact. Stopping there to contemplate the next moves. I’m applying plenty of pressure to the ring gear when turning the pinion to get the mesh to show up.

I'm no expert, only done half a dozen setups myself. But it seems to get progressively worse.

I want the contact patch in the middle of the tooth because 460 van on D44. Now I gotta play with back lash and see if I can get the contact footprint better. I think I’ll delete the last change and go from there. The early thumb print contact is ok but it’s all the way out to the weak end of the tooth on the drive side.

So back to this and play with pinion depth slowly? Maybe .026 pinion shim gets you where you want to be for backlash if 009 isn't it.

Unless it's got like $5k of turd polishing going on everything else on the axle is gonna pop a bunch of times before the ring and pinion. :flipoff2:

It is supposedly getting a lot of turd polishing. 450 hp of overlanding glory. They are looking at E4OD builds to take the new 85% hp increase.

:lmao:


And then they're gonna do fancy suspension to make it good off road. And then they're gonna complain that it handles like a drunk pig during the other 99% of the time it's on the road.

There’s stuff that’s happening in an order that isn’t how I would do it. But I’m doing this in trade out so my involvement is minimal. They want me to setup gears in these housings. I’m putting an ARB in the rear. Fully reassembling them… then they are going to take them to a sandblaster. Then they plan on taking them back apart to replace rotors and drums.

I kinda get the order. Doing brakes last and on the car does kinda make sense. But that whole step by step **** just doesn't make sense when you're paying someone every step of the way. Probably would've been better to just pay someone to build the axle from start to finish and swap it out.
 
First off, those pics are way to clear..you need at ****ty lens filter. I would probably start with your first pattern and tighten the backlash up to .006 and see what happens. It doesnt matter after they sand blast the axle anyways...some people.

:laughing:

This is setup numero uno but with .006 BL.

I can make it worse from here but messing with it doesn’t make it better than this. Yella marking compound starts drying up the second it’s opened. Marking compound is getting too thick.

.000 shim between the pinion and big pinion bearing. .006 back lash. Everything is to its right tolerances right here, pinion pre-load, carrier pre-load. So going to press the new bearings on it and send it down the road.

That's on the money right there :)
 
I didn’t document moves. The D60 gear pattern was much easier to find because of it driving on the correct side of the toofs. The Vevor case spreader is bad ass for the $ hundo it cost. The vevor clam shell bearing puller is also bad ass for the $ hundo it cost. Van D60 with external shims. .045 under the pinion. .006 backlash. .012 pre-load on the carrier bearings.
