bought my truck with 38k got 46k now but did notice a slight vibration when I bought it in the column and could feel it on the pedal nothing like the 06 I drive at work, have looked at my joints didnt seem to be a problem, did notice I will be needing to get my front end pinion seal replaced but for now ill just keep a check on the fluid. cant really pick out exactly what it would be its not making any noise atleast none i can hear over the 5" exhaust, have been feeling around for it while driving where its most noticeable mainly around the 60-65 range under real light throttle, there is no tranny shimmy or popping just a vibration i can feel in my wheel and in the pedals seems like its coming from the front end, any ideas or ways to rule certain parts out, I do feel it some also when coasting but then there is still transmission in that mix to, Im just looking for an idea and trying to make sure i dont end up on side of the road about to haul enclosed trailer 6k down to florida for work just trying to make sure i cover all the basis and not missing something

 

u joints for sure could be all of them even the front axle joints. for some reason on the 06's they seem to be more of a problem!

 

thats what I was thinking, It seems to be much more pronounced when in third and forth gear

 

also which u joints are recommended I cant seem to find much clarity on which to go with I have always used spicer in my old jeep and scout but not sure which to go with on a 3/4 ton serviceable or not I would think serviceable would be better but then the seal wouldnt be as good because it has to push the old grease out somewhere, any suggestions

 

If its a rumble type of noise, one of the rear U joints is usually the culprit. One of mine went out at 35000, its rumble was most noticeable at 70mph+ with very slight load. There have been some tips posted here on how to check them, just don't recall the details off hand.

Rednax, so you did use AAM U-Joints again? Still satisfied with that choice? How was the balancing on your driveshaft....was it close or did it need balancing? Im in need of u-joints soon and I believe that the DS needs to be checked also for balance. Thanks!

 

im going to drop my rear driveshaft and check the joints again tomorrow im determined its got to be somewhere behind the trans from where the vibration starts

 

i had a vibe at those same speeds, i just did mine with spicer 1410 non serv. joints and a new carrier bearing. make sure u paint mark the shaft and splines as to reaign the shaft the same as it comes out or u will need to have it rebalanced. ps. vibe gone.

 

Are most of you having vibrations with the 2 peice shafts? Anyone having issues with the 1 peice shafts? Spicer 1410 non serviceable joints, wonder if they have a serviceable that fits.

 

mines a one piece rear d/s its the front joint behind the transfer thats gone bad on mine

 

they do but even spicer will tell u they r weaker.

 

jetfuel, thats what Ive heard too. I have an early bronco that I did some research on the front axle u-joints and they did tell me the serviceable ones are weaker. Spicer still the way to go though? I know on the 1/2 ton stuff there are a lot of choices but some are just WAY too expensive.

 

I just had my rear ujoint replaced in the last couple weeks. I was having a really hard time figuring out what end the vibration was coming from-front or back.

I pulled into an old parking lot that was covered in ice-and let er rip. I found that doing a ice burnout was a really easy way of distinguishing between the front end and back..

After I determined that-i put the truck on jack stands and put it in drive to watch the driveshaft-and verified it with a pry bar. The u joints were too tight to move by hand-but a prybar made it clear as day.
