When is it too much?

[bdegs]

So I put a doubler in my K5 and pushed it up flat with the frame. Needless to say this made my rear driveshaft angle horrible since the shaft was now shorter and the rear output of the case was at less of an angle.

In an attempt to get a better driveshaft angle I cut my spring perches of the Dana 70HD and welded them back on. Problem is I didn't follow the measure twice, then measure again, then weld, rule. After the truck was back down on the leaves the pinion sits at 23#.

My question is: For a weekend warrior what is the max degree you can run a pinion at before you start burning up the bearing? And, if I am past that max degree is there anything I can do besides cutting the perches off again?

Thanks for any input

My friend back when I lived in Ohio ground the knuckles on his dana 60 in the front and rewelded them for better pinion angle. So we drilled a hole in the top of the diff and tapped for a 3/8 pipe plug so we could put more fluid in there so the bearing always got lubed. Easy if you think about it. Just used a screwdriver to check fluid level.

Sounds like an option. Anyone else have any thoughts?

There are no concrete numbers on how much pinion angle is too much. I've seen 15 degrees before but that was for a high pinion rear.

You can put shims in (backwards) to lower your pinion angle.

If I were you, I'd overfill it some and run it.

Just not too much if you drive at high speeds. When it starts blowing out the breather vent it's too full. Don't ask how I know.

I have about 60,000 miles on mine rotated up higher , and its a 12 bolt

I use heavy synthetic gear lube .

had this happen to me as well. Made a big mess.

Yea, luckily I left all the extra lube in southern CA instead of up here. It also helps to fill it up on flat ground instead of a sloped driveway.

Your is higher than 23#?

What lube do you use?
