when i shift i feel a clunking/jerking letting off the clutch, if i dump it, it really jerks hard, but i feel the driveshaft moving while driving, it has play in it when i move it with my hands...so whats going on with the drive shaft....? is also jerks the whole truck around(3800-4500) shifting to 3rd...anyone know whats up..all help appreciated

 

Sounds like the U-joints are in need of replacement. Will cost you about 15 - 20 bucks for the U-joint and its not that hard to install.

 

Sounds like u-joints, but you really need to be sure. With the e-brake on, grab the driveshaft as close to the rear end as you can, and check for play. Pay attention as to whether or not the pinion has any play, or if it's all in the driveshaft.

 

hey thanks again guys , i will keep ya's posted if i have anymore problems...i appreciate the help

 

Could be the clutch on its way out too, I've had many stick cars and trucks shake and jerk due to wasted clutch and pilot bearings/bushings. But definatly check the u joints first as they are cheap and can be replaced with a bench vice and a couple of sockets. I just finished a 96 that the joints were so wasted on that there were no needle bearings left and the cross was worn about halfway through.

 

thats crazy....i just went under it and it's solid back towards the rear and has play more toward the tranny...i'll be back with some more info hopefully

What tranny? OD? Granny first gear? Can you read the door jam sticker trans code?

i think its a t-18 4sp with OD and no granny, trans code B on the door jam...thanks for everyone's help

 

No, the T18 is the super tough cast iron monster with a granny gear. I believe you have the TOD which I have yet to personally see as they were known to be a POS and they didn't survive. I would be super grateful if you could snap a pic of the trans and shifter for my ford tranny records.

 

thanks for the interest in this adrainspeeder...i will borrow the g/f' s digital camera and see if i can post... could i also look for some letters on the tranny? i have 3- 87 150's, 2 straight 6's and my toy the 302,And an 85(auto), but they all have the same four speed, i'm still trying to get the 302 to shift like butter.thanks again for the help
