disc rearend to drum rearend..straight forward swap?
Thinking about trading a local guy my disc rearend for his drum rearend. Is it basically a straight forward swap? Or is anything different needed? Brake booster? Brake lines? And advise would appreciated.

It will all be straight forward if you get the whole thing from him including the brake lines. The only thing im unsure of is the emergency brake cable. Im pretty sure if you unhooked it from the side of the frame about midways back you would be alright though.

disc to drum swap has been covered in the stickys.

The complete rear should swap right out but only if its the same model of truck. Example a standard cab short bed may have different E brake cables then a single cab with a long bed or even an extended cab short bed or crew cab with a mini bed. Other wise its basically a straight bolt in swap.

To answer your question Yes. same housing, same axles, same gear size.
Only things that might be different would possibly be the gear ratios and the possibility of having a locker.
The brake bias is also different between the drums and a disc. I believe drums require more pressure so the original drum truck might see an increase in brake wear on the truck originally equipped with drums. It may also lock up under hard braking.
Someone local that I know swapped from drums to disc and reported this issue to me after I helped with the conversion. At first he was upset and wanted to put an inline manual control valve to even it out. Now he has decided to live with it and tries to brake slowly and smoothly. In 1 year he managed to use up at least 75% of the rear brake life. One side was not wearing evenly. I believe the cage was slightly tweaked on the reman calipers. He has since replaced the caliper assembly and they are now wearing evenly. But it still seems he is going to be doing breaks on an almost yearly basis.
