Mark Farage has laid on the ground and had people drive over him to try and figure out which u-joint was bad.

 

[Bang Bang]

I don't think I trust anyone enough for that. I'll just remove the d-shafts.......

 

[Bang Bang]

Well, it wasn't the tires. I'll be dropping the front drive shaft tomorrow hopefully.

I'll run over you, mike!

It's the least I could do.

 

[Bang Bang]

That will tell which driveshaft needs new ujoints if you have a bad one. The vibes should go away when you pull the offending d-shaft. There's a diff-lock work-around if you don't have the switch.

The Center Diff work around you refer to, is that the 7 Pin mod or is there another way to do this? I do not have the CDL switch on my 97.

Use the hazard light switch for now. You will have to modify the CDL connector slightly but it works great. Just remember that with the hazard light switch unplugged you will not have turn signals.

I was thinking you could put it in Lo (which locks the CD), unplug a connector somewhere, then shift back to high range, keeping it locked.

I'm not finding any info on it though.

The trick is to put the truck in low and wait for the diff lock to engage. May have to drive it a short distance till it locks. Then pull the CDL fuse and then shift back into high range. It should stay locked until you replace the fuse and reverse the process.

Awesome. Thanks guys.

Good way to get home if you twist up a driveshaft!

I've got the d-shaft bolts soaking in PB Blaster as I can't break them loose. But my wife drove the truck yesterday and said something that I don't know why I didn't notice before. When driving and the truck is shuttering / vibrating, if you take your foot off the accelerator it stops shaking immediately. What does that tell you?

 

[MEMCruiser]

Drive shaft U-joint is bad?

 

[wngrog]

Ujoint.

 

[Bang Bang]

Thanks for confirming.

 

[MEMCruiser]

Wahoo I learned something all these years.

Let Rob rebuild both at same time.

If I was anywhere near him I would but as I am in NO I don't think it will happen.

I brought the truck to the dealer as one of our members is a service manager there and they put it on the lift and said they recommend I replace the entire rear drive shaft since the cap is cracked on one of the joints and the hole could be wallered out now. Anyone have a rear drive shaft for a 97 FZJ80 or LX450 they can part with?

 

[Bang Bang]

Oh, and I got the center diff locked this morning using @Bossman 's technique. Once I get the rear d-shaft off, can I drive it for any period as a front wheel drive without issue? Thanks again for all ya'll's help.

 

[wngrog]

Missing cap. That will do it.

 

[wngrog]

Yes you can. It will drive odd but it's doable.

JRob has a parts 80.

 

[Bang Bang]

I don't know how much odder a box on 35's with no front sway bar and an under-powered V6 can drive......but OK.
