Front driveshaft angles...

[cuervo]

I been running front driveshaft angle through my mind the last couple of days and have some basic questions about reducing them.

If you press off the in knuckles and then rotate the house so the pinion is point at the tcase and the set the knuckles back on at the stock degree, which I think is something like 5 or 6, do you stand a chance at drying out the pinion bearings?

I know they make shims, but I've always been told that changing the caster will lead to poor drivability.

I know in smaller lifts say 6 and below it dosen't seem to be much concern about driveshaft angles.

So, what's the stroy from you side of the hall?

you can doa cut and rotate, you will have to run more oil, but the tail beaing is going to see less oil, theses bearings see failure on normal aplications from lack of lub, i would just keep a good eye on it, you have to figure what is worse drive line vibs or reduced pinion tail bearing life

You can cut and rotate the knuckles or drill out the plug welds and rotate the pinion.
I have yet to see an oiling problem leading to bearing failure.

Do not shim the axle. Your caster will be off and you would be turning into the ground rather than side to side.

I have shims in the front. THEY SUCK. Cut and turn if you can. Also I havent had any oiling problems with either pinion bearings

I doubt you would have an oil issue , fronts are part time on most rigs , and not many people put more than a few thousand miles a year on their front in a good year .

If you felt strongly about it , you could run thick synthetic fluid which clings to surfaces .

So many of us have plenty of miles on rear axles with the pinion pointing up to the transfercase . And the rears are not part time .

I have 2.5 degree shims in my front 10B... with my 7.25 shackles, the pinion is pointed a tad couple degrees below the driveshaft yoke. I haven't noticed any steering difference than when shims weren't there before. Maybe I'm so used to my truck.

The only real concern on the front shaft is that it doesn't bind at any given time. You will be at such a slow speed that you won't have any vibe issues. I think you would be hard pressed to remove the outer C's from the tube at home anyways. Those things are pressed on with like 15 tons IIRC and then welded.
