still having vibration issues especuially at 60 its real bad but for some reason round 70 it evens out. my u joints front an rear are new. my driveshaft slip yoke end was beat to hell from i guess the previous owner so i replaced that end of the driveshaft but I still have yet to get the driveshaft rebalanced. idk if this would makea big difference but im still going to do that. what else you all think i should do? rotate balance tires, get front end alignment. anything else. thetruck only has 50,000 miles so i wouldnt think bearings or balljoints andstuff would be bad already.

 

balancing the tires would be the first thing i did...

 

i was experiencing the same problem

but the problem disappeared after i cranked my torsion bars ( maxed out )

 

Have you checked your pinion angle?

 

how would this be thrown off with just like 50,000 miles on the truck

 

my truck has 80 000km on it (roughly 50 000 miles) and i have to replace my upper right control arm because of a bad ball joint... don't rule it out... factory sealed (non greasable) ball joints go way too fast...

i would say probably 70% sure, your driveshaft needs to be ballanced... also, when you took it off of the yoke, did you put it back in the same position, or is it possible it was rotated? that could cause it to not be balanced also...

 

well when you take it off it has a blue stipe down one of the teeth and that lines up with a mark on the driveshaft, and trust me it wont glide in and out easy if its not on perfect. I have already found this out the hard way and when you put it on in the wrong groove its a ***** getting off. but yes I know its in the right way im just figuring it needs to be balanced because thats the end that has the weights and it was weighted for that other driveshaft so im sure not every driveshaft is weighted exactly the same just like the same rims and tires if that makes sense? i had my tires rotated and balanced and an alignment today and he said my tires hadnt been rotated in forever and the front two has a chop in em which is going to still cause alil vibration even tho they got moved to the rear now, but I can see how it changed alil for the better but still having some vibrations. I think its prrolly just a mixture of alot of small things you know. Oh and what would be the best way to check the ball joints and things like that to see if their still good? Also my shocks are originals so their prolly about gone too, whats the best shock on the market for our trucks right now?

 

jack the vehicle off the ground, i can't remember if suspension has to be at full droop or not, i don't think so, but the wheel can't be touching the ground... have someone hold the steering wheel so it doesn't move, try to turn the wheel side to side (as if you turned the steering wheel side to side) you are looking for play... if there is play here, that is tie rod ends, try to wiggle the top of the tire in and out of the fender, (use some force) this will be upper ball joint, try the bottom towards you and away, this is lower ball joint, now get a pry bar, put it under the tire, and pry up and drop it a few times (again, looking for play) i beleve that is wheel bearing

every driveshaft is ballanced before being put onto a vehicle, so every one has a spesific amount of weight on it... just like tires, you NEED to get your driveshaft balanced... and i wouldn't wait long to do it...

 

thanks for the info im def going to look into this, and yea I have been meaning to do it and I was going to do it yesterday with everything else but I ran out of time but im going to try and go get my driveshaft balanced tomorrow. the place is just like 30 min away and I work nights so im always lazy and dont get up in time and go all the way down there but IM really going to try to tomorrow. also any info on the best shocks to get.

 

I would say that is your problem...

 

yeah yeah i know im def going tomorroe but i just didnt think that the smal weghts n jus that small end of the driveshaft wud really causethat bad of a vibration issue but i cud b wrong.

 

1oz - unsprung weight = 10 oz spring weight... driveshaft = at best semi spring... (partially spring, partially unspring)

BALLANCE THAT **** YOU **** STICK ****ER!@!!!!!
