During some time spent acquainting myself with my wife's newly acquired '98 Disco I noticed that the front driveshaft did not have the u-joints positioned correctly, or so I assume. I've always made sure that u-joint yokes are phased 90 deg from each other so as to eliminate the variation in velocity induced by the angle on the joint. The rear driveshaft has them correctly positioned. I've noticed no unreasonable vibration but I still wish to make it right. Unless they are purposely set this way? If not, I'm getting under there and indexing that shaft until the u-joint yokes are situated perpendicularly to one another. Anyone tell me otherwise?
Thanks,
Ken Dunnington |

Personally, I'd say "If it ain't broke, don't fix it". Meaning, if you're not getting vibes, I'd leave well enough alone. I have heard of people getting vibes after lifting, and then re-indexing their shaft to help some, but no reason to mess with it at this point. You may be opening up a can of worms. |

ken,
seams logic sometimes messes with ya on Disco's
I too had noticed this on mine and posted my laugh at LR responce...it turns out that because land rover did not set up the trucks with the proper geometry in the front driveshaft to begin with that they had to index the front drivshaft to counter the effects with phaze.
pretty stupid in my book ...but it is what they did so everyone needs to take it into account when making upgrades
no wonder so many people have vibe problems |

OK guys, thanks. I'll leave it be. Muskyman, that is humorous. I suppose they did not keep the output shaft and the pinion shafts roughly parallel and that's what was 'fixed' with the out of phase yokes, eh? Oh well, no plans for lifts or anything like that here, so as long as the factory set-up works, I'm happy.
Thanks again,

Ken:
Had you tried to rephase your front driveshaft, you would have found it to be extremely difficult to do so without the legendary BFH! Rover has included some mistakeproofing techniques which make it difficult to do what you had suggested without some more work.
Consider yourself fortunate to have asked before trying!

Yeah, saved me alot of time this ole computer and this board. I figure I'd of discovered the truth after messing around and not being able to get it "right".
I'm a LR newbie, but not a newbie wrencher so the BFH was retired awhile ago.
I currently own:
'51 Willys/'77 Scout II hybrid
'53 Dodge M43
'55 Pontiac Chieftain
'57 CJ5
All were acquired as non-runners/parts cars, ie CHEAP! Two are drivers, two are still projects.
I like this Disco. I'm glad my wife chose it over the other vehicles we were looking at. The more I read about it, the better I feel about it too.

ken,
I have been a scout guy forever and Disco is about the only truck I have seen that covers as many bases as a scout does.
there are a number of really similar characteristics in the two as well, one being that common 4x4 sence will take you along way with them.
welcome to the BB here, I think you will find as I have there is a really great group of people here |

And I live in Solihull for Scout owners, Fort Wayne, Indiana. And, I used to date the daughter of the VP of Engineering for International Harvester.
Maybe I'll take some pics of my Rover out in front of the old plant.
Peace,

Forget the Scouts, I wanna see the '53 Dodge!  |

Hhmm, Yes, I still live in Fort Wayne, but I work about an hour South of the Fort.
As for that '53 Dodge, I have the perfect engine for it, a 354 hemi... Been sitting in the garage of my rental house for almost ten years-probly stuck bad though. |

Well I'll have to get pics of the Dodge. Not much to look at at this time as I'm focused on the mechanics of the whole thing. The M43 is the ambulance version of the M37.
A hemi would be nice but I like the really heavy stuff so I'm putting in an IHC 392 with a T135 5-speed trans behind it(7.17 low, direct 5th), then on to the stock divorced NP200 transfer which dishes out to the original Chrysler 9 5/8 diffs(5.83:1) with custom axles($$$). The axles are the weak link on these. A guy in Germany who likes the M Dodges made up a half dozen sets of 300M axles, not cheap but worth it. He also makes vacuum lockers for it and completely new front axles/tracta joints, saving my pennies for those. Power steering is by 'armstrong' but will need to upgrade with the 39-41" tires going on, stock was 9.00x16(~36"). Disc brake conversion to get rid of the horrid Lockheed drums.
For the time being here's a link to a photo of my IHWillys, I built it because I had a Willys with a crap frame and a Scout with no body after a roll-over.

I'll get the pics of the Dodge one of these days, I have to go up to friend's place where it's at. It won't fit in the garage or backyard and my neighborhood covenants don't allow long-term projects out front.

muskyman, I'm not sure what is meant by the six red dots...?
The T135 I have does not have an e-brake drum, just a VERY large yoke. The NP200 transfer in the Dodge does, though it's the old style band type, certainly more effective as a park brake than e brake.
BTW, the 392/T135 combo tips the scales at about 1000 lbs, they are heavy!

The word T-R-A-N-Y is blocked for some perverse reason |

yes they are REALLY heavy.
the one I run in my scout is actually a agricultural pump motor that we bought outa a farm field in iowa where it lived pumping water most its life.
the AG series blocks are 18% nickle and where the first "impreoved cooling" style blocks out there. they also have 100% forged rotating assembly.
I used a 12 1/2" in loadstar truck clutch that weighs 90lbs. the off idle torque is just unreal,it took 35spline axles to keep from snapping them at every blurp of the throttle |
