I found out " the hard way" that I'm gonna need to upgrade my driveshaft to a 3.5 aluminum shaft. Any suggestions on where to get a good shaft ?
-
HA junk yard works. What are you using it for besides connecting the trans to the rear
-
if you destroyed your last one, ( and you actually did not run over something and destroy it ), I would make sure the new one is balanced before putting it on.
-
Ok, so whats anyones opinion of the aluminum drive shaft vs the stock ones?
-
Aluminum is lighter. They are larger diameter because they are aren't steel. Nothing wrong with them tho. Lots of newer diesels use aluminum shafts. I'm going to get an aluminum shaft for my truck. Just haven't gotten around to that part yet.

What are you running for a drive train?

The aluminums are probably better, but cost more $$$.
-
I was quoted about $350 for an aluminum shaft with new joints from a shop that has been in my area for a very long time.

If Vile catches me asking about driveshafts he's going to ask me if i did what he told me to do first. I have a little humm in my driveline and need to do a 180 with the rear pinion, then try a hose clamp on the dshaft and see what happens. I guess i'll try all that and perhaps change u-joints as well.
And speaking of,,,how in the world do i find the RIGHT U-joints for my driveshaft? What info do i need?
-
I think that little humm is getting worse, used to just feel it at 40 mph, now it almost feels steady at 30 mph. It feels like it is under or behind me. In park or neutral its as smooth as butter.
In fact, I feel it less as soon as I take foot off gas (when doing like 40). I wonder if slip yoke is worn bad, after all..i DID just have that leaking weep hole problem.

Yeah, I saw that place, they do look good, prices not too bad either. Custom made, 4 weeks before its ready though. I need it NOW.

You are way to excited Philo lol. Your gonna have to paint it black so it looks factory lol.
-
Always been my problem, too exited and impatient!
-
Ever have a problem fix itself? I could barely, if not at all feel the driveline humm on way home from work. Great, now what? I guess just wait it out. (Could be calm before storm) lol
-
You need to have a coke and take a chill pill. Your gonna blow a gasket lol. You just got a new engine that runs perfectly. We don't even know if what you feel is normal, it could be completely normal and your trying to fix something that isn't going to go away.
Breath in slow, deep breathes thru the nose, exhale slowly and completely thru the mouth. Haha

After this little driveline humm, i swear i'll be off the stuff for a while. And with the nice weather coming, it will be tough. Lol
Actually i'll be pretty busy to about july 1st. Trout season!!!
-
I dont get it, the humm/vibration i HAD is now near totally gone. It slowly went away more and more. I guess the Lord does sometimes bless in mysterious ways. Ever have a problem just work itself out?? IDK...
-
Philo,
Breathe slowly....iiiinnnn..... and ooouuuttt......iiiinnnn....... and ooouuuttt......
-
I know man, i gotta think before i act!! The humm is back in my driveline. Vile said do a 180 at the rear of it, will try that first. I'm not panicking, but thats the last thing thats not working perfectly on the whole truck. I'm so close...
-
Hey, whats inside the tranny where the slip yoke goes? O-rings, seals, bushings??
-
Depends on the model but yea, all of the above.

Stopped at this little shop in Temple yesterday to have a tire fixed. One of the fellas in there is making these. " Wasn't there at the time" He had one completed, an one he was working on. If your still looking, I can probably get ya some more info..
-
Making what, a custom driveshaft? I did find a place not too far that does a full test on dshafts. You have to take it there, spin balance, ujoints, slip yokes, etc. And all is repaired on site. Or they make you a complete shaft on site.
