tried to search and couldn't find what I wanted.

I have a 10.5 rear (glovebox says so) It is making a clicking sound so I am guessin it is about to head south.

Am I better off rebuilding this problem or try to find a salvage 11.5?

The truck has 101500 miles and fluid was changed every 15k w/valvline synth

This truck and I really have a LOVE/HATE relationship going

If you're gonna keep the truck I'd try find an 11.5" LS (if u can find matching gears to the front diff)

I would pull a 11.5 from a junk yard.... Gears should be easy to find as all fronts are the same.

thanks

Thank you for the input guys, I lucked out kind of, it turned out to be a roached 2-month old NAPA rear u-joint. for some reason two of the ears never got grease, and me being the terrible mechanic that I am never noticed this...well lesson learned :$::w:

yep

yep lucked out on that one the local Stealor Burgunder Dodge quoted me $2054.98 FOR A REAR END REBUILD!!! got me looking for the problem elsewhere real quick!!!!

Still have my eye out for a 11.5 because power will be going up and other research I have done lead me to believe these 10.5 are weak

True, the fronts are all the same size (9.25) but not the same gearing ... I was hinting to make sure he looked for matching gears is all. Wouldn't want 4.10 in the rear and 3.73 in the front would ya?

lucky for you nutzio!

right, and what I meant was basically 3/4 and 1 ton's have the same gearing options... so finding the same gears should be easy enough...

03 and 04 SO 2500's had the 10.5" rear. All HO's and 04.5+'s, and 3500's have the 11.5.. Now the only thing with a 10.5 is a 2500 gasser.

I can send you pics if you are really interested, but I learned on the forum to check the tag/sticker in the glovebox, and yep says it plain as day 10.5 w/3.73 axle ratios...

ohhh and I am a old Jeep guy (now semi retired) so I know ya need to make sure the ratio match up.. had a 01 TJ w/custom f&R d-44's w/ detroits spinnin 5:38 gears...

I have a pair of 79 Ford F350 HP d60 front and a d60 rear w/ 4:10's in my back field, I should just do a rear disk brake upgrade, but I know from experience on a newer truck easier said then done:$:
