The restoration/modification of Daisy.

We got home at 1:15am today. Moab 4x4 outpost took good care of us and we left Moab at 5:15pm.

Daisy did really well, I left the programmer plugged in to monitor trans temp. Two of the mountain passes on I-70 warmed it up to 215*, one time I had to stop so it could cool down. We made it home without issue except for being exhausted. Today we rest, I'll unload everything later.
 
Glad y'all are back and everything functioned well. Bigger cooler coming?

Daisy has fallen into disrepair. (my version of it anyway). I've spent so much time/money on the Toyota this year that daisy has been neglected. In her defense, she's pretty solid and doesn't ask much of me. But there are a few things going on that need to change.

The radiator leaks, again... These damn Champion radiators are junk. It's leaking from a tube a few inches in from the drivers side tank. Every time the fans kick on I smell coolant, it's starting to get the frame and drivers side spring wet. Radiator Express (who I ordered the radiator through) has been cool about it, I'm going to buy a different radiator from them and they're going to refund the difference. I keep reading about people having great luck with the OEM big block radiator (spectra CU730) with LS swaps. It's bigger than what I have in there now and with some oem parts, will drop right in. So when the new radiator gets here I'll figure out my fan mounting and send this shiny all aluminum junk back.

My new transmission leaks. The pan gasket seeps all the way around, has since the moment we filled it. I want a bigger pan but they're expensive so this one might take a while. What bugs me the most is that the underside of my truck was clean and dry for years. Now this trans pan has a coating of oil and dirt on everything under there. Unacceptable.

Finally, ever since we had the new trans installed, the truck vibrates worse than ever before. It vibrated before but it's noticeably worse now. It's only slightly better when off the throttle. I start feeling it around 50mph, it gets worse at 60mph and doesn't go away at 80mph like it used to. My dogs can't even sleep on the floor when we're on the highway. The driveline is in phase, t-case output and pinion input are both solid, no play, u-joints are new. It's got to be angle related. Granted, that didn't change when the trans was replaced, not sure what the connection between the vibration and the new trans is.
I checked some angles this morning, on the rear diff I found the pinion is pointing up 13*. The eng/trans/case are pointing down 6*. Measuring angle on the case itself is difficult as most of it is inaccessible due to my skid. I was able to put the angle finder on one of the cast ribs on the case and get a photo of it where I couldn't get my head up there to see it. That 7* difference could be the whole problem. I think I'll get some shims and try that.

Absolutely the angle difference will cause or exacerbate vibrations. Also double verify that the yoke flanges for the u joints are in line. Kinda looks like they are from the pics, but make sure they aren't a spline off of inline.
 
Almost looks like the rear pinion is pointing up, past the angle of the driveline. I'd shim the rear axle down some so it more parallel with the t-case (assuming you have a slip driveshaft and no CV joint).
 
Can you spin the yoke and put the angle finder on the caps of the U joints?
I was told that would be the most accurate way to read it.
 
Yeah man, your rear pinion is almost opposite of what it should be. At least looks that way in the pics.
 
Did they change out the trans mount? Remember to leave a couple of degrees in there for housing rotation too.
 
Scott take the drive line off. Then measure it all. I measure on the yoke itself.

But yah that's a pretty solid difference. Should help the vibes alot.

Tranny pan gaskets. Literally the bane of my existence. I can't seem to get one done right. Of course I've never had a new pan. That completely solved the problem for a buddy.
 
On my 4L80, everything except the factory style steel silicone impregnated gasket leaks.

I tracked down vibrations for months and never found a single cause, but several contributing ones. One at a time, I ended up shimming the pinion down, tightening the output yoke, and rebalanced the driveshaft. All good after.

I went to 4wp and got some 6* shims. They looked at me like I was crazy when I asked for leaf spring pins. I hate 4wp...

After I get the rear axle shimmed tomorrow, I'll drive it and see how it feels and maybe have the driveline rebalanced. I put some more break in miles on the yota running around henderson looking for spring pins. Didn't want to drive it all the way down into Vegas to Skip's Spring Service. I'll take the wife's car down there tomorrow, it needs to have new tires mounted anyway, they've been riding in the trunk for a couple weeks. So as they say, two birds.
 
I used to work in the shop at 4wp and the counter guys have always been idiots. Dwayne works in the shop. He knows his way around trucks.
 
Lately I've noticed that my rear springs are sagging more than they used to. I think towing the Toyota around has put a beating on them. At ride height with the trailer loaded up, my rear springs are super flat, add camping gear in the back of the Suburban and they invert. If the springs are wearing out that could make my pinion angle worse as they're bending into an S shape. It might be time for some new rear springs. Which sucks because I want to do ORD springs but don't have the budget for it right now. I've got 3.5" springs up front with a 5.5" shackle netting about 4-4.5" of lift. The rear has a 4" shackle flip and a zero rate, netting 5", and it sits lower than the front. Not saying I want it to be any taller, I just think it proves those rear springs are shot.
