I have a 9 1/4" rear end and have just installed a new Detroit TruTrac junking the old stock crappy LSD and it's retaining clip problems.
It's had all new bearings, pinion seal etc and new oil.
I have 100 easy miles on it at the moment and babying it.
What I'd like to know is, how hot does the pumpkin get, if you do 15-20 miles at 60 mph?
Obviously stuff is still "bedding in" but, when I place my palm on the stock diff cover, it's very hot to the touch.
It has not had the gears replaced, just what's mentioned above.
I don't know how hot the old stock LSD and diff got.
So any help comparing it to a stock LSD would be appreciated.

Bump???

Anyone put there hand on their stock lsd axle and pumpkin and let me know, how hot it is after a 20 ,ile run please?
Al.

 

I just got back from my local Lowes. About 20 miles round trip. I just put my hand on my Differential and its pretty damn hot to be honest with you.

 

That's just what I wanted to here Toefur.
Many thanks for the help bro'.
Looks like this is normal then and something not to be worried about.
Cheers bud.

how much it run you to get the DTT put in?

 

Well, over here in the UK is was like £200 quid sterling.
At todays exchange rates, that would be like $353.
Don't know how that compares to fitting prices in the USA but, finding someone over here with the necessary experience of these Dodge Axles in the UK, is worth the money.
He also replaced the pinion seal & crush sleve along with axle bearings and caps etc
I got the DTT from Moe's Performance........hats off to Bob at Moe's here. Excellent service and a great price!

The axle appears to be "bedding in" fine and I must say, the truck feels VERY smooth to drive.
None of that shuddering from moving off or at slow speeds around corners that the old clutch pack LSD used to do.

wow, for $400 it sounds like a deal. I odn't have any LSD, and it's embarrasing when it rains and i have to drive in 4wd cuz. or when i leave only one tire mark
