Betty's "I want to be a mule" progress log thread

[Turdle]

Bug's bugs and more bugs--

Sheri went for a spin around the block last night and upon return Betty was dripping coolant. Seems we used the large water neck clamp at the smaller radiator neck and it started weeping. At least now I know where that clamp went--

Removing it required draining coolant. Went without a hitch. I then wanted to wsh her up so I went to the car wash which saw me coming because it broke right after I used the foamy brush. I stuckk all the remaining quarter in it out of desperation but no dice. So, I had to jet home and unroll my garden hose for a rinse. I was pissed so I hung note on the carwash ill changer telling the guy to fix his S&^t or go out of business, but either way quit coming down to empty quarters and split-/rant


ON to this AM. She squeaked at me. So, I thought it might be the cam sensor but after removing the serpentine I discovered it was the alternator brushes. Some fine sand paper fixed that, but whoa what's this? blood? kinda looks like blood but no, it's transmission fluid on the skid plate. hmmm. Looks like whoever ( yeah it was me) tightened the transmission fittings was getting hungry because I gave them another 1/4 turn and the leak stopped.
So, might as well get this flush out oil out of there-did that and dumped the entire oil filter contents onto the front skid plate.
Fast forward through a roll of paper towels and I finished up the oil change. Got it all back together and Sheri wants to take it out for an A&W burger and a root beer float.

I stuck the front drive shaft back in and still get a real fast vibration starting about 60 MPH which was not present without it. I did notice the front slip yoke slides out quite a bit. from where the front yoke attches to the front diff, the yoke "could " slide back bout 5-6 inches. Like it is near the end of the splines??not sure if this has anything to do with a vibration but the shaft sure could be longer. I do have a longer yoke from f150 I could use a conversion joint in-

Maybe I need to send it out for balancing?

Did the front drive shaft angle change from the new bump stops on the skid plate? :scratch:

Hmm, that could be a big part of the vibrations some people have, and others don't. The front diff, should be unchanged from stock, the pinion angle.

Good thought, I wonder how much the two angles differ, if the two end shafts are parallel?

Fix this first! then report back.

Same vibration as before I removed the shaft the first time. Nothing to do with the transfer case or angle. It isn't moved that much anyway.

5-6 inches of slip yoke travel might be an exaggeration. But 2-3 inches would not be.

Make sure the socket end isn't 'wallered out' now. I would think you would only want an inch or at most 2 inches left for compression and reserve most of the travel for extension (droop).

I had a 'wallered out' socket end and it resulted in a vibration.

The slip joint needs to be quite tight but still able to move.

 

[MrQ]

On a second gen you really don't need a slip joint. Both the diff and the transfer case are bolted in. The only reason its there is to compensate for flex in the frame.

If you have that much sliding in and out there is a problem. Mine doesn't move more than an inch at most. I would see about getting a longer drive shaft.

Bad engine diagnosis

Well, there's your problem

Cylinder 1 is to the left

Globs of piston stuck to the combustion chamber dome

Here's what it looks like now

Parts I can powdercoat or use for scrap art

Ouch! Nice chunk made into mush

The Autozone story is all to familiar. A neighbor of mine manages the closest Autozone. He admits that their computer system is horrible. I only go in there for fluids, sprays etc... and that's just to make small talk with him.

I like NAPA, but from what I've heard they're going to transition to a similar system

I've already experienced that problem with NAPA back in April. I had to replace the drive belts on my '02 KIA Sportage and noticed an idler had a rough bearing. NAPA was the cheapest place by quite a bit. I go to get the idler and it's a V-Belt idler not a serpentine idler. KIA changed from a v-belt to idler in 98 or 99 but their system says they are all the same.

The guys did go out of their way trying to find me one. They even called a dealership. I ended up going right across the street and ordering one from Advance.

Even after telling my wife she could be the first one in town with an engine coffee table she said "naw"

I'm now glad I talked you into changing motors after that pic!

Yup! Me too!

For process of elimination I am going to measure flange to flange and take the front drive shaft to inland drive lines up in Olathe, Ks. I already talked to them, 150.00 for a correct length and balanced drive shaft.

Is your truck on stock body mounts, so the shaft would be the same as mine in length? I obviously have not installed mine yet, but it would be great to compare lengths of other trucks with the BW4406 in them.

What length is your front shaft now, and what are you aiming for?

I'll go measure mine shortly, I've got it standing up in my garage along a wall. I think mine was around $175 total also, to have it made given two used shafts to work with. He supplied the new slip joint and one end flange I believe.

Not sure if it makes a difference but I have a manual 4406 transfer case, not AWD

pictures coming

 

[Turdle]

This picture shows what I think to be 4" slip yoke travel with the shaft installed.

In this picture the other end of the tape measure is hooked to the transfer case end flange, So, I assume I need a 34" drive shaft?

I can compress the drive shaft down to 31" with some force and it would go a bit further if I could hold it there while measuring.

I only need it to compress to 33" or so for installation

Also,does anyone know if the front drive shaft with Double cardan ( cv) should be parallel or cross phased?

Driveshaft Selection

Go to his Tech Info section and it illustrates all the proper geometry.

With the way your pinion yoke looks it looks like you may just need a single u joint shaft.

Everything else you could want is in the tech section too.

That is what I was saying in the beginning of having this issue. When we had the non lifted black mountaineer with a 4406 installed there was no cv needed and it drove smooth. Taking another look from transfer case to front diff it is a very straight shot. I still do not see why I should need the double u joint cv double cardan thingy.



I'm going to have them make 2 joint front shaft without the cv end.
