Now that spring is here and its getting warm outside, it became apparent that the trans cooler i installed just isnt going to cut it.
Not exactly small by any means. This is actually the largest cooler Ford ever put in these old trucks. I use one for the E4OD in the green '96 bronco, but its not quite up to the task that this truck is demanding.
So i did some digging around online, and found this beast:
It is a monster of a cooler, and consumes most of the real estate behind the grill:
...it does fit in there pretty good though:
This thing is a beast. Immediately knocked 30º off of my trans temps compared to the other cooler i was running. So this is going to do the job nicely.
After finding this, i decided that it wasnt worth a failure on the trail, and ordered some better shafts
Seems the Yukon shafts arent up to the task, so i ordered a set from Moser Engineering:
In the interest of strength, Moser does not machine their shafts for spindle clearance, instead they have this nice smooth transition. So i will have to verify that they clear the spindle , and if not, modify the spindle so they do. Odds are that since its a D70, they will clear just fine.
We'll get some paint on these things, and get em installed later this week!
New r&p installed. Apparently the ring side carrier bearing had spun on the carrier, and the new bearing would slip right on! Fortunately, we were able to find a local who had a two-piece D70 carrier so we ran over, picked that up, and got it all done and back together.
I forgot to buy gear oil. Also still need to reinstall the drive shaft & anti-wrap bar. Im also in the process of replumbing the OBA since i routed it a bit too close to the passenger header and blew the line during the cam break-in. At this point, its just the rainy spring weather slowing me down.
