Yup the trutrac is a nice piece, thats a 14 bolt unit MUCH bigger than the 10 bolt we all have, this is the 10 bolt


and congrats looks like the truck is coming along nicely

 

youll definately be happy with the new gears!!

 

Thanks for the comps gentlemen. I know that I will have a competitive ride, but I know I will never reach the stamina that most trucks have now like a turbo or the juice. I'd like to learn what the truck can do without making an experiment out of it. I try and keep it conservative since I have a house note like many to take care of.

 

Here is a shot of the new guts going it.



Now to get technical:

The ring gear bolts are a left hand thread and require a 3/4 inch socket. The torque spec for them is 65 ft.lbs. There are 10 of them, and they need to be tightened in a criss-cross pattern.

and as always NEVER use the bolts to pull the ring gear on

 

Question from the novice...what is that gold stuff in the gears? Or is that just glare?

 

appears to be Ring Gear marking compound...it allows you to see the contact pattern when the gears are set up.

 

Thanks alot I appreciate the fine work..I'll recommend you to thers anyday....Road smooth didnt hear no whine no nothing but man it sucked driving no faster than 60 MPH the whole way home...

 

Alright, before stabbing everything in, I had to check and double check the pinion shim thickness. Since I have done 4.10s MANY times, I know that .035" to .037" shim works.



Once the pinion is in, I install the differential and check the backlash. The specs for these gears is 6-10 thousanths. This one hit right at 7 thousanths.
