Fully polished TuRD

Good to see you working on instead of parting it out. Bummed I’m not making Choccolocco. Next time.

 

Yea I have shaken out of that funk. The house deal can always fall through!!!


You are lucking out with this time to buy another place tho!! If I still had my old job we would be refinancing for sure. It would not be good to try that now with one income and me spending money on getting my gig going.

 

Hey are you still running the 80 axle in the rear? Have you had any driveline vibration issues since installing it?

I'm trying to track down a nasty high speed vibration on my 80 axle that I think may be made worse by the offset diff.

 

I am and was chasing vibes for a long time. Turns out I thought my driveshaft was in phase but it really wasnt. I followed the instructions in the youtube video below. I went from almost 10* out of phase down to less than a degree and no more vibes. All the angles have to be dead on with that offset.

For 19yrs I thought I knew how to phase a driveshaft, I realized I didnt after watching that video! No more eyeballing shit or using a tape measure, so much easier doing it this way.

My other suggestion is to only use OEM center bearings. With the offset it tears up the cheap Amazon, timken, Spicer parts stores one QUICK. I got less than 5k miles out of a timken one.

 

Yeah I eye-balled my driveshaft, it looks like it's in phase but I'll inspect it closer to be sure. My center bearing has a few miles on it, might be time for that as well. Just crazy that I went from no vibes to pretty bad ones just swapping axles.

 

Check that phase with an angle finder you may be surprised! I thought mine was close as well. Make sure the pinion angle is good as well. I went from very minor vibes to insane vibes after my SAS, even after I had the 80 axle in there for a year. Insane vibes like the entire transmission would violently shake back and forth on the highway. I moved the trans mount and it would still kind of do it, but still visibly shake the trans. I followed that video as a last chance before I burned the truck to the ground and I'm now down to minor vibes. I think that offset just causes the shaft to start whipping around and resonating and it just compounds.

 

Man I really thought that I screwed something up when I set up the gears, glad to hear it might be something a little more simple to fix. The compound angle is definitely pushing the limits of what that driveshaft can take, hopefully I can get it tuned so it's bearable on the highway.

Thanks for the insights.

 

I think it's more the flex in that center bearing causing the issue, but its not something I would really try fixing with a solid one. Its definately bareable now up to 80, especially empty. If I'm loaded up for a wheeling trip it vibes a bit at certain speeds but that's kind of expected.

 

Yeah I've looked at the "wookie strength" pillow block bearing as a replacement for the center bearing, seems like that's a recipe for more vibration though. I wonder if the transmission mount is a culprit as well. Everything is suspect.

 

I've had the 80 axle for 3 years or so with no vibes with a bunch of highway miles, I just put 250 miles on it last weekend and no problems. I think it's all about making sure that the driveshaft is phased correctly and pinion is pointed at the carrier bearing with a double cardan joint on it. I may have just gotten lucky but I set my pinion angle with a 2x4 end on the flange and pointed it at the carrier bearing and I'm probably a couple inches taller than Slander. I do have a traction bar that cuts down on axle wrap significantly that probably makes a difference too.

 

I think the trans mount in my case wasnt helping the situation with the duals, I noticed a difference when I moved it to the rear case and went back to a rubber mount as opposed to the poly one that I had in there.

 

I have the pinion pointed at the carrier bearing, but it looks like the u joint phasing is off by 1 degree or from the rear joint to the double cardan, and another degree from there to the t-case u joint. I wonder if that’s enough to cause the issue. There’s not enough adjustment in the slip yoke to make that fine of a correction, so not sure what’d I’d be able to do about it.

I think I’m gonna throw some parts at it and see what happens - trans mount, carrier bearing, and rear u joint. My favorite method of fixing problems.

 

So no wheeling trip because each day is worse than the previous one it seems LOL!!

Really lucky I dont have a big pile of square tube here, I watched some videos on someone building a flatbed on a first gen truck and now the gears in my brain are turning.

 

I just want to say the coronavirus can kiss my dick. Whatever that person ate over there better have been the best meal ever consumed by a human being because it shut my wheeling trip down. Fucks.

Rant off

 

Preach.

Fucking sucks to have to call off a trip planned 9 months in advance

 

Agreed. I was supposed to go on an epic snowboard/camp trip to VT this weekend, obviously can't. Want to go camping this weekend still but it feels socially irresponsible even if it's going to be with only 2 other trucks.

 

has IL shut down the borders yet?

 

No, im sure they will want to shut them to stop the normal ammount of people fleeing this place LOL!!

 

Sign of the apocalypse, the tacoma got some LED lights put on it today that I have had in my garage for 3yrs.

I'm mentally cracking as evidenced by this mod. #endthelockdown
Crappy weld porn, these are the tabs, just glued then to the side of my winch mount.

I still need to wire them up. I'm going to try to reuse the elocker switch as a light switch. That is unless I have to rip the entire dash apart to get to it, then I'll just put a regular 2 way switch on there.

 

Lights are now functional, end of the world inbound. The cali raised harness and switch are fucking retarded. Who puts a lighted on/off switch on a harness that goes right to the battery?
