Status: offline 		Ok, i just pulled the rear diff out to change the grease that factory put in it to 3k silicon. Now my problem is when i put it all back together the pinion gear makes a winning noise it. it has not been ran sence i have done this so i know i did not ruin the gears. It has shims and i put them back the way they came out if that helps also it had some thick grease on the gears. what did i do wrong. thanks

Status: offline 		I know this has more then likely been asked in this thread, but I don't have time to read through 36 pages.

I need to know how to make my CRT turn sharper. It don't turn well off power (it will turn around in about a 10" circle) but on power it won't turn for nothing (but I'm using 30K in my center diff but I'm about to put thinner oil in it)

My tires are towed out (maybe 2 or 3 degrees) and I'm, running a 3.5 in the back (don't know what its called)

Status: offline 		Whats an ackerman? Sorry its been a while since I've worked on my CRT.

How dose thicker center diff oil help on power steering? the tires are barely touching the ground as is.

Status: offline 		it will send more power to the rear, allowing the rear to slide instead of the front, in turn the slower spinning front tires will get more traction and the truck will rotate through the turn better.

It is normal for the diff to make some noise but the diff should operate smoothly. If you're rotating the diff and feel it get tight at any point you need to move a shim over to the other side. The manual says start with 2 and 2. My diff shims for example are 3 and 1. Every diff is different. Make sure to put new grease between the pinion and ring gear and that the pinion is seated all the way back against the diff housing.
