okay guys..after the vibration that broke the yoke of my rear driveshaft..I replaced the drive shaft...Im still getting really bad vibrations..Im going to replace the u joints on the front drive shaft...I tried pulling the front driveshaft..but the shaft kept turning..any tricks on how to lock it in place..and how to remove it..Also looks like there are 3 u joints..autozone shows on 2 ...any ideas on that..
also when driving..the truck wobbles..when slowing down the steering just moves from left to right about 2 inches..like a wobble affect..
any ideas on that..
Also when driving my shifter shakes and vibrates like crazyyyyyyy
One more thing is my brake light is on..but my emergency break is all the way down..but the light stays on
Thnx in advance..

 

45 views and no one has any ideas??? Come on guys

 

are your u-joins in phase?

 

brake light on: under dash, isnt there a switch to toggle the light on and off???? check brake fluid level?

wobbles: alignment? brake issue? TRE issue? bent tie rod? any play in your ball joints?

do you have a lift that distorts the pinion angle? maybe try shimming...

 

has new joints on the rear drive shaft..
truck pulls to the right..i know the alignment is out but not that bad..
Lift wise..its all stock..

 

More than likely...

Did you match mark the flanges and replace them in the exact same spot?


Pulling means it needs an alignment... Pulling to one side has nothing to do with the rear DS...

Unless a rear drum is dragging...

 

thats where i messed up..I did not mark the flanges..only read that after i removed the damn thing..do i have to get it balanced? i am going to do the alignment soon..
just need funds..i know there is a writeup on here about doing it urself..but i dont know if i would trust myself haha..

 

Well... You've got a 1 in 4 chance of getting it back right...

 

thats exactly what i got..if i have it balanced..would that fix the problem..also i see that my pinion seal is now leaking..i was just going to put some rtv sealant on it and put it back on..

 

no... and don't remind me.. I have a bad mid-shaft bearing and I think that's what lead to my last diff failure... It was the pinion...

Remove the stake nut and flange and put you another one in there.

 

is your truck a long bed?

 

yeah long bed

 

check yer mid-shaft bearing...

Darn things are NOT cheap...

 

midshaft bearing??? thats the bearing on the front drive shaft between the front and back u joint??? the one under the dust cover??

 

Negative. That's called a Cardigan? Or CV joint... (see sun visor)

The mid shaft bearing holds the middle of the rear two piece drive shaft up.

 

the drive shaft is one piece i thought...it connects from the rear diff to the transfer case..nothing else is in the center..

 

i vote get it balanced, my camaro had a good shake in it and pulled a little bit when braking, got the ds balanced and it drives straight, stops straight, and has no wobble (they welded 4 big washers on the thing)
