it's a work truck and a play truck. when it's not working, i can't play... um borntoloze: i thought you were outahere? the angles are factory set. there is no way to change them without screwing with the motor mounts. furthermore, hurst drive-lines PDF files say that a driveline issue is usually felt at lower speeds. that was the problem before i replaced the driveshaft. balancing the rear wheels makes sense because a vibration there will go to the driveshaft. having said this, i'm going to buy a *******ed angle finder and check them asap but please note that this is a factory truck, not a hotrod build. the angle of the trans is the same as it was before the trans swap. the ONLY thing that could slightly change the angle is the trans mount but only IF it pulls or pushes on the trans. i've check the mount twice. the trans mount would have to push really hard because when i get under there and try to move the trans up or down, i can't budge it. my feelings on the matter is that pinion angles are a red herring and if they were off, the vibration would be evident at lower speeds.
so your vibration is really a noise and not something you feel in your **** while your driving i'd say, i did follow your other thread, a few years ago i pulled the three speed on the tree trans out of my 64 GMC and installed a truck 4-speed on the floor, i cut out the floor and installed the tall trans cover, the 4-speed also came with a big rubber donut that sliped over the shifter and was sandwiched between the top of the trans and the bottom of the trans cover, never had a problem.
my 1984 Chevy 1/2 ton (350 w/ th350) had a vibration I couldn't find even with a new built driveshaft... I moved the trans mount crossmember from the top of the frame to the bottom of the frame and it was smooth as silk... don't think I even had to drill new holes.... Jay in Texas
jay: that's interesting. first things first though. gotta get my floor down and seat in this morning. then i'm going to look again at that trans mount to make sure it's not pushing up or pulling down on the trans. then i'm going to drain my trans fluid again and get my tires balanced.
Dragsta hurry on down to Florida I can get $250 just to have you committed to the nut house.I"ll fix your truck while they try to fix you!
Plenty of part supply catalogs out there,I`m sure one of them can save the day for you. The only thing I`ve been unable to find is ambition.
Hey borntolose, take a deep breath, now exhale! Dont let this guy get to you. Some people have to do things the hard way!!!! Save what little sanity you have left!!!
borntolose... we all have to be off our rockers to mess with these old cars. Im gonna write a book called "How not to build an old car". It will contain chapters like... If it aint broke dont break it" and "If you keep having to remind yourself, RIGHTY TIGHTY, LEFTY LOOSEY, find another hobby"
what EXACTLY is your pinion angle?.... no more of this lets put a body lift ******** on to cure a drivetrain vibration ****! hell man if you don't wanna or can't diagnose the problem, take it on up to frisco and let the guys there help ya out. they did offer after all. i've known guys hellbent on replacin a fuel pump to fix the alternator but this is ****in ridiculous. either take the help you need or stop beggin advice you'll ignore for **** sake!
Seriously. Ryan, you need to do something. Dragsta is a grenade inspector, and he is dragging all of the other grenade inspectors to a new low. We need something powerful. Dragsta, i seriously suggest you review your trigonometry or geometry. Particularly right triangles and angles. Pinion angles are factory set until you change how it rolled off of the ***embly line. Is the t5 longer than the old three speed? if it is, and the angle has not changed, then the tail shaft would be noticeably lower. measure the angle your ****** is sitting at, and the difference in height should be (difference in ****** lengths) x Sin(angle ****** sits at) Maybe your going to prove all of us wrong, but i have my doubts when it comes to nearly four thousand years of geometric knowledge that the Greeks started. How long before the ban hammer gets dropped. This is making the H.A.M.B. look bad. anyone know why Holeshot got it?
Dragsta, what Giovanni is saying is that if your old ****** had 4 inches between the output shaft and its mounting flange, and the new one has 6 inches, your pinion angle has changed, and even though the mounts were set in place at the factory, the pinion angle is now different. If that measurement is exactly the same on both trannies, and their overall lengths are the same, only then can you say that the pinion angle is set from the factory. An angle finder is only about $10 +/- and I've seen them in the bargain clearance bin for a couple of bucks. It's cheap enough and you'll find yourself using it for a lot more than just checking pinion angles.
Also, I don't know if it's got anything to do with your problem, but I have E range tires on my work truck and those ****heads at the oil change place are always pumping them up to 60, saying that they NEED to be up that high or they won't stay on the rim. ********. I NEVER have anything heavy in it, and the higher the tire pressure, the ****tier my traction on wet pavement, but most importantly, the bumpier the ride. My 1500 Silverado gets TOSSED around the roads when the tires hit an expansion joint or a pothole with that kind of pressure...and everything feels like it's vibrating. Unless you're hauling heavy loads in that, crank them down to 40 or 45, it rides so much better.
boy there is no shortage of ***holes here in this forum. borntoloze should thank me for giving him a reason to get out of bed every morning and all of you "pinion angle" folks aren't listening to me. THE ANGLES CANNOT BE CHANGED WITHOUT ****ING WITH THE MOTOR MOUNTS OR PUTTING A LOT OF PRESSURE ON THE TAILSHAFT OF THE TRANS. the problems were.... •drumroll•...... #1. a trans that wasn't bolted properly to the belhousing because the idiot used the wrong bolts. #2. an out-of-phase driveshaft #3. the trans pushed up into the floorboard #4. the wrong bolts used on the trans mount which wouldn't tighten up. #5. some people here at the HAMB who got me sidetracked on NON-ISSUES because they don't listen. the solution; ... •drumroll•...... #1. get the right bolts for the trans with an allen wrench head. (thanks to some helpful folks who helped with that) #2. get a new driveshaft built. #3. redo the floorboard. #4. get a new tans mount and install the right bolts. also modify slightly the trans mount to make sure it isn't pushing or pulling on the trans. #5. stop listening to disrespectful people here who don't listen and are stuck on pinion angles WHICH IN MY CASE CAN'T BE CHANGED BECAUSE THIS IS A STOCK ****ING TRUCK WITH A STOCK ****ING MOTOR AND STOCK ****ING MOTOR MOUNTS AND THE ANGLES DIDN'T CHANGE BECAUSE THE MOTOR AND BELLHOUSING DIDN'T CHANGE AND THE MOUNT TO THE BELLHOUSING WASN'T ALTERED. HOLY MOTHER ****ER!! SOME OF YOU FOLKS NEED TO GET A *******ED LIFE.
yes, i drove it into town this evening. the floorboard modification made a huge difference as did the aforementioned fixes . i covered a huge hole at the bellhousing with sheet aluminum screwed to the floor and spray-glued a thin piece of rubber over the entire trans cover and hole fix, then put insulation and carpet over that. my only concern is that the bad initial trans installation screwed something up. i suspect (if the bearings are in fact bronze" that is was the metal in my trans fluid. going to change it again tomorrow and then soon again after that.
