Measuring Driveshaf Angles

[dhcomp]

Ok, so this is an easy task, and i've struggled with it.

Have an angle finder.

Going to unbolt the driveshaft at the rear axle yoke, and measure across the flat yoke mounting surface.

Any tips on measuring at the trans end?

I used the cooling fins on the side of the tail housing on my t-case when I did mine years ago. On the rear end there is a flat spot parallel with the pinion on the side of the housing you should be able to use w/out dropping the driveshaft.

I'm assuming this is your burb we're talking about? If so once the shaft is removed from the t-case just put the angle finder on the end of the output shaft. If you wanted to come over tomorrow I have a digital angle finder you could use which is alot more accurate than those cheap pendulum type (I have one of those also).

Didn't think of removing the shaft from the case. Good call.

I'll try it out on sunday. Want to make sure its loaded down with standard gear to set a baseline angle.

You shouldn't have any issues with it being a burb though as that's got a pretty good length shaft which means small angles compared to a blazer.

Now that the rear end had been totally rebuilt, it's the only source left of the vibes im getting.

So i dont know if its safe/advisable, but is it possible that you could remove the rear shaft and drive the truck in front wheel drive onto the freeway for a mile or two to see if the vibe has gone away? Just to for sure nail it down as the source. Also i dont know how old your joints are but i was under my burb the other day and was checking stuff out while i was down there. I noticed that while the u-joints appeared to have no rotational slop, i could rock the shaft up and down on the axis of either cross shaft on the joint. Did that make sense?

My joints are new, and I'm not going to run the truck up to 70+ in front wheel drive.

If you had vibes at 40, ok, but not that those speeds.

Yea probably better to just not do that.
