Dana 60 Trash-lok question - Pirate4x4.Com : 4x4 and Off-Road Forum

ScottB · 11-15-2005, 09:28 PM

Hi, i have a 70 GMC 3/4 ton with a dana 60 in the back. I pulled a trash-lok from an 84 ford f-250 at pick and pull i assumed was also a dana 60 (full floaters on both). Anyhow, it had the same gear ratio as mine 3.54:1. so i went to put it in today and used my stock ring gear on the trash-lok carrier and got it so that when the pass side bearing and race were almost seated, the drivers side was still over a 1/4 inch above being seated. i put the caps on and tightened it down a little, and resistance got to be so much on the driveshaft that it was quite obvious it was binding...

what it looks like to me is that the ring gear is bottoming out on the pinion. If i shimmed the carrier towards the pass side would this fit? or did i get screwed and get a dana 61? When comparing the stock open diff to the trash lok- the trash-lok has a thicker flange that bolts to the ring, and the ring itself is thicker than my stock open diff... when i swapped the ring that came with the crack-lok it was even further from seating (half an inch)... what's up with this? i search for like an hour and found nothing.

all of these are off the donor 84 ford f-250...

Did you double check that it was not a Dana 61????

ScottB · 11-15-2005, 09:33 PM

at the time i had never heard of a dana 61... when i got back, i searched for what the hell limited slip i got and found it to be a trac-lok but was then appaled to read that some trucks had a dana 61. no idea on the difference...

SJscouter · 11-15-2005, 10:48 PM

i would check to see if it was a dana 61 also,
and theres a good reason they call them a trash lock

the carrier itself is very weak, and it isnt uncommon to brake the carrier in half, ive seen it many times and i broke one in my scout II a few years ago.

Yea, better double check the axle. There were a bunch of mid 80's F250's with the dana 61 in them.

b454rat · 11-16-2005, 02:58 PM

Don't know if this is true, but I know that 44, 60, 70 and maybe other Dana axles have a stamp on the lower section of the diff. I looked at an axle that looked just like a 60, out of a 78-79 Ford, but it didn't say anything. After checking the gears had to be a 61.

Saurian · 11-16-2005, 06:58 PM

Yeah, unfortunately the 61 can be found in cases marked 60. What was ford thinking...

ScottB · 11-17-2005, 03:43 PM

okay went back to pick and pull today and looked at the ford donor- it has a slightly different case than the dana 60 in my truck. so i looked around and found a dana 60 from a 70's ford f-250 that also had a trak-loc in it. pulled it, pulled off the shim pack on one side and put the shim pack from my diff on it to see if it was close- installed, checked the tooth pattern and damn if it wasnt dead on. so i am about to test drive it. i'll post up pics of the bad donor rear end. anyone want a trash-lok out of a possible dana 61?

i thought dana 61's werent floating axles?

b454rat · 11-20-2005, 12:38 PM

They had both. Found a ff out of a 78, and a semi 8 lug with a some sort of posi, both with 3:08s.
