tranny ? again

[5.0Flareside]

well tomorrow im going to my dads house and we're gonna double check all the motor mounts and tranny mounts and make sure the Trans Crossmember isnt loose. and we're gonna check the u-joints also.

and if all of this is good im gonna have the tranny serviced.

and if its still vibrating ill get the Flexplate done.

i bet havin the trans service won't help anything...

 

[5.0Flareside]

i bet havin the trans service won't help anything...

the main reason im gonna do it is it needs to be done anyways. and i was talking to Brad and he was telling me bout his old 97 that had vibrations and shutters and he said he changed the Fluid and it fixed it.

so i decided i might as well do it and hell if it fixes it well than it was worth it. if not oh well it needed to be done anyways.

i think we figured it out. Driveshaft Center Support.

 

[SuperCab]

AHA! wow I never even thought of that...


The '74 has one and I've had to replace it before...

 

[5.0Flareside]

yep. i didnt either till me and my dad got up under it and started playing with the driveshaft and compared it to his 95.

 

[5.0Flareside]

ok now having the problem of how do i get the shaft out of the bearing? it goes to a certain point and just stops.

 

[5.0Flareside]

ok ive got it all the way down to just the inner most part of the bearing is left. and its pressed on and am having a huge problem getting it off. heres the pic.

 

[Skandocious]

Looks like someone needs a press Yes I've replaced it before it's definitely pressed onto the shaft. I used a press to get mine off and I think I would have had a real hard time without it.

Heat it up and then beat it off.

 

[SuperCab]

x2. take the torch to it than a BAMF hamer it'll pop right off.

It's good to have the new one pressed on, but not necesary...

 

[1985 Ford F-150]

I dont have a press so a 80 pound vice and a BFH works for me. I rebuilt my transfer case that way and aint had a problem.

 

[5.0Flareside]

well took it to the tranny shop for them to finish removing what was left of the old bearing. and then they pressed the new one on...

guess how much they did it for.....



















ZERO DOLLARS!!!!!!!!!!!!!!!! cause im a repeat customer multiple times.

 

[smokey]

Hard to beat that price.

 

[5.0Flareside]

nope. all i have in this is the 20 dollars for the new bearing. ahaha and a few hours of labor.

 

[Skandocious]

So is the vibration gone or what?

 

[5.0Flareside]

GAWD DAMMIT!!!!!!!!!!!!!!!!!! THAT MOTHER****ING VIBRATION IS STILL THERE!!!!!!!



ugh im so freaking pissed.

 

[5.0Flareside]

WOOOO!!! im pretty sure Brad figured it out. he called me and gave me some tips and one was to make sure the U-joints were in "unison" like all 4 points on all of them be at say 12,3,6,9 oclock. well i went out and check and ill be dammed. mine werent. so tomorrow after work im gonna go and take it all apart again and put it back together correctly.

 

[Skandocious]

Yeah, Brad called me after he talked to you and we agreed that'd be a good start.

The big question I have is-- did this vibration start when you swapped in the new axle? If so then that narrows it down quite a bit. Couple other ideas if the u-joints don't pan out: is the pinion nut tight? Is there play in the pinion? (might need a new bearing or bushing). I also replaced a brass bushing that was in the tail housing of my transfer case (you probably have one in the tail housing on your tranny) when I was hunting down a vibration-- that could also cause a vibration like you're saying.

I don't think the flexplate is your issue because my understanding is that this is only happening at higher speeds. Everything forward of the transmission is completely speed-independent. The only things that spin at different rates with different speeds are from the trans-->back.

Start with the u-joints and report back.

tranny ? again

Sounds like a rough night at the bar...

Heat it up and then beat it off.

...not the tranny, I hope...
