Heres my deal i had a shop change my gears in my 97 ram 5speed, i had a dana 80 limited slip unit for a 3.54 because i knew you had to change the carrier for the rear my question is do you have to change the carrier for the dana 60 front when going from 4.10 to 3.54, i have been driving it for a month know but today it snowed and i put it in 4wd and when i was driving it it shook real bad and when i kicked it out of 4wd it quit, anybody have any ideas not setup right or was he supposed to change the front carrier your help is appreciated

 

And both gear sets were changed to 3.54/3.55 and it binds up running in 4wd. If you were running in lock on good (non slipping) pavement they will bind some. Owners manual advises not runnning in lock for this reason.
If shop was able to set up, the carrier should be ok.

You say you "kicked" out of 4wd implies was binding up from running on good traction surface. Generally if back up a few feet will come right out.

 

Sorry no help but....do you still have your 4.10's?

 

yes i have some 4.10's anyways it was on ice and snow its not binding up so to speak it has a vibration when i get over 15 to 20mph, it was not there before the swap is it coincidence that the front driveshaft might have a bad u joint, when i disengage the 4wd the vibration stops instantly, i have owned 4wd's all my life and this is not common.

 

wait you do still have 4.10s up front? if so thats your problem you will destroy a lot of parts running 3.54s/4.10s, if you changed both Id def. check out the ujoint

 

To the best of my knowledge, you don't change carriers until you hit 4.56's

You should use the same carrier from 4.10 to 3.54.

Are you sure the guy swapped BOTH sets of gears?

 

give me some credit hintz i have a 1000 horsepower pulling truck i just have never messed with swapping gears,

 

im confused by ur post. Are u still running 4.10's in the front? If so, thats bad news using 4x4 with 3.5's in the back.

The dana 80 needs the different carrier when going from 3.5's to 4.10's. The front Dana 60 just needs the gear set.

 

ok I say check; ujoints, output shaft on tcase, and pinion/yoke

 

this being a diesel truck site i kindof figured you guys would use common sense and i did not have to explain the whole process now why in the heck would i put just 3.54's in the front what the crap would that gain me, use your heads guys its not a hard question i finially got ahold of my differential specialist and he confirmed that i do not have to change the carrier for the dana 60 unless i go to 4.56's, thanks alot

 

Well ur whole post was a single sentence, so I got a bit lost in it. And its not out of the question for someone to only change the gears in one axle and not know any better.

 

thanks man for the info doesnt matter if its one sentence i was in a hurry, i appreciate all the help though i know alot about these i have built 30 or so trucks i jsut dont mess with gear swaps i do horsepower and thats about it.

 

Is the front drive shaft in phase?
