thanks to DeathCougar, there is a new clutch working in my 4x. (4 hours including test drive- )

however, upon reattatchment we found the driveline to be very tight (fully compressed)

or it looked fully compressed, and it did go back in, but it needed a prybar to get it over the rear diff.
?.....so, main question is (and time will tell too) will that damage the tranny/or anything else?
?....is anyone elses driveline (tranny to the rear end) really tight on re-install ?

btw.
88 v6, 3.0 4x4, extracab. (seems very original)

 

Yeah, that happens sometimes. The slip spline got pulled out a little when you removed it, or while you were storing it. They can be hard to compress back down, and/or hard to extend for that matter. There's a partial vacuum you have to overcome inside the slip spline. It takes some pressure to squeeze the grease around, or push air in or out of the things usually.

I wouldn't worry about it.

 

Problem was tho, when we re-installed the driveline, it was compressed ALL the way. the rear wheels where also off the ground, so it should have been slipped out a bit. but it wasn't.

the spline wasn't pulled out at all. It was up and tight, we had already overcome the vacuum, and there was only about 1/2" from collar to collar. the Splines bottom out at that 1/2" so you dont do damage to the yokes on full stuff.

Anyone have an 88 V6 truck they know is 100% original who can measure their driveline??!

 

Oh, sure thing. The stock rear driveshaft on my 88 V6 4x4 long bed(112" LWB)pickup w/MT is a one-piece measuring 42.5" from weld to weld. It's actually replacement #2(not really the original stock driveshaft)but they have all been exactly the same size as the original.

I guess an ex.cab with the same engine/tranny/t-case combo would have the same size driveshaft. They are the same wheelbase, 112" LWB. In fact, the one I have on there now could very well be off an ex.cab for all I know. I didn't ask, just measured to be sure it was the right length.

 

I think it was the mechanic.

 

Yea I think you are right. So there ya go dan, take some measurements, and see if you have the right driveline in there.

 

Thats pretty true. I lengthened the driveline when he wasn't looking, then painted AND aged the paint.

Damn im good!

 

upon further work (done today), i looked at the driveline again, and it now has opened up again.

so, we did fully compress it, but it somehow uncompressed about 1-1.5 inches.
and i feel alot better.


thanks for all the help, and the measurements, i will measure them this week.
(got the interior out (firewall-bed is now bare metal)- rework in progress.

 

bump

dirve line and wheel base for the ex-cap and long bed is the same for the 1st gen trucks.

 

hmm thats wierd. Maybe having the suspension at full droop caused it to move slightly forward? I dunno, thats odd. As long as its working now!
