did a 8"/3.07 swap and now my driveshaft rubs the dust cover the one by the slip yoke, well its rubbing the inside the trans dust cover by the spline... anyone else have this problem... i also lowered the truck 3"... if you had this problem what did you guys do... cut the shaft... thats seems like the only way out... thanks

 

Mine didn't rub... Maybe your dust cover is out of round...

I went from a 410 to a 307 on the same drive shaft, changed the flange at the diff to fit my shaft..

My drive shaft did seem slightly into the trans farther but mine didn't rub, just check to make sure your dust cover isn't bent. What did you swap from? 410?

 

I bought a tacoma 4x4 driveshaft and it has double cardan u joints and a slip spline. I haven't had any problems using it (when I was static).
Some people cut out or modify the stock driveshaft. But doesn't it need to be balanced?

 

on my driveshaft its the end of the dust cover thats rubbing... so its round... i went from a 7.5" 3.58 gears... and all of my 4x4 driveshafts have flanges on both ends not a slip on one end... so how did you make it work.. and if you cut minimal and line your yokes back up...you usually dont have to get the driveshaft rebalanced...

 

Is the driveshaft bottoming out in the trans too? The 8" diff is a bit bigger so a shorter shaft may be needed...

 

Oh I miss understood your swap, I thought you went from an 8inch to an 8 inch. I havnt swapped from an 7.5 to an 8 before... I know the diff is longer, maybe that's your issue.

Like b.y.e said, drive shaft bottoming out. Get a drive shaft from a trck with an 8 inch,

 

yea it bottoms out in the trans... and as far as getting a driveshaft from a 2wd with a 8"... i took the only rear end around here and when they pulled it they cut the driveshaft i forgot to request it..

 

they cut the driveshaft? i think thats harder then taking the 4 bolts outta it...

 

it is a bunch of mexicans that only have a torch and hammer for tools...

 

well...go hit the junk yards and get a drive line...pretty sure it will fix your problem. I would measure yours first that way when you pull it you done end up with the same length...or just have it cut and ballenced. its like 150 bucks here, IDK where you are at but should be somewhere around that.
