Hi folks, after having the truck on the road for a few weeks, i discovered a grinding, whining, clonking noise out of the driveline. As my truck is a GMC longbox 1/2 ton, i have the drive shaft extension in it. I already ordered the u-joints, the bearing etc., but examining the second yoke, it seems like it got damaged, due to loose and broken bolts. Now my question, would anyone of you guys have a good used yoke available, might deadzone have stuff like this? I really want the truck to be on the road again soon and be reliable, as summer won´t last forever Thank you all for any help or trace...
JOE To The Rescue ! Yes Joe will have what you need . What you need to do now is : take the old bad parts and lay them on clean cardboard etc. so there's good contrast and send him photos of what you need . Be sure to count the splines and tell him how many...
Pictures... Thank you Nate, for your reminder; stupid me, forgot to include the pictures i already made. Here they are, hopefully you guys can see, what is important. I counted 10 splines...
Lucky me Nate, a buddy of mine, (he´s a milling/lathe machine expert by trade) came by on the weekend and i showed him my damaged and rounded yoke and asked for his advice. He told me, to weld on the missing millimeters and then take the yoke on a lathe and turn it down smooth to the desired dimensions. For a vehicle with an output of about 90 horses, he wouldn´t see any issues doing this. I gave it a go on Saturday and i think, it´s nearly as good as new again and hopefully the rest of the parts show up soon; can´t wait, to take the truck for a spin and it should be much more comfortable to drive. Thank you anyway for asking, if all failes, i would contact Joe for a replacement, but shipping stuff from the USA to Germany is unbelievable expensive at the moment. A parcel the size of a cigar box is caculated about 30$$$ I´ll take a picture and show you the result.
Journeyman Repairs Good ! . I'm glad to see you took this route , I hesitated to suggest it because it takes a Journeyman Machinist to do the job , .002" off and it'll shake like a paint mixer forevermore.... Having access to good help is a real gift .
Here we go, with the reworked yoke; i think i´ve welded on about 2mm (0,0787inches), that´s what i thought was missing, compared to the front yoke on the tranny. After the welding and slowly cooling down, i turned the surface down, to smooth it out. When this was done, i took the yoke on the milling machine, to cut the center part to the exact measurement (1inch). Hopefully it´s good to use again another 50+ years By the way, what does journeyman repairs mean? In the meantime, i added a "new" accessorie to the truck... An old oak wine barrel, ment to be the tool box and dry storage area.
Oaken Keg That's a nice tool box there . Journeyman means one who's a fully competent at his Trade . I'm not really good to explain things , I hope that helped . Similar to " Maestro " in many other languages .
Back together Since the missing parts showed up lately, i´ve put it all together. The "okie" bushing wasn´t available, so i made one on the lathe. Now i took the truck for a little spin and checked for leaks, as i changed the automatic oil also, while everything was apart. My concern/question is, how hot can/should a closed driveshaft tube get, in normal driving condition? I tried to touch right at the joint after the tranny and i would say, it was nearly as hot as the tranny case, after about a foot, it was just worm? Is this normal, or might the bushing be to tight? Thank you alls once again, for any help on this.
