Found the 205's weak point. the output shaft is sloted in three places. Apparently for lubrication. this is the third or fourth one this truck has shattered.

What does everyone think about tig welding the lube slots back shut re-machining it and drilling a smaller hole in their place? would it need re-hardened?

Also I took a picture of the dana 60 front outer that broke within miliseconds of the 205. :D

Lets just say there is alot of torque, wheelspeed, and a skid involved. I know they make a 37 spline output for the 205 but at $800 Its a bit pricey.

get hold of jp conversions...they have a 32 spline output without the slots.not terribly expensive,but not cheap either.makes way more sense than going to some wierd spline count.

if you tig the shaft and remachine,it'll break 10 times faster.full heat treat will be required for survival.not worth the expense imop.

Thanks Ambulancechser I will be ordering one of these today! I knew there had to be something more out there for such a common transfer case. I hope they can get it to my door before friday!

David, Fyi the last one lasted just over 15 seconds so I was grasping at straws and figured I'd try anything. and yes funny.

ordered the shaft from JBconversions today. wow $75 for next day air!! It had better get here tomorrow.

Yep Sled pulling. I can't say too much about the motor but it's a Big block with custom headers outside the framerails with 2-1/4" primaries into 5" collectors and it needs them.

your welcome...if that shaft starts to go on you...consider getting a new one cryo treated before use.
with the rear output problem solved,the fronts will start to go...then the inputs.

when the proper level of insanity is approached...the cases blow :nuke:.it takes a TON of power to blow a well setup 205 (or lots of axle hop and a heavy foot).after that there's nothing for it but a monster rockwell or a custom gear or chain final...

have fun.:beer:

Brown santa came this morning!! bounce

JB conversions did good. They got it sent out and here. The part looks great. I just hope I'm not posting pictures of it broken by the end of the weekend. Crossing my fingers.

Mid 80's and newer 205's use the better output. You should be able to get that output shaft at any tranny parts supplier.
what makes them better? is that the shaft that JB is selling?
