i was affraid that it would crack :oops:

Crack where? the only machine rod that is available was 110mm OD - plenty beef - even at 75mm long. But hey whatever's available to you.

Yeah, but think of the flywheel effect on the downhill stretches - those 'last year's technology' drum brakes will struggle to pull it up! :rofl:

All BS aside, good on you Scott, that spacer looks real good. I have respect for people that make stuff for their own rigs, instead of parting it out and buying stuff off a shelf and having someone fit it for them. That's half the fun - built not bought.

But he bought it :finger:

(he just skimmed a little bit off the out side - afterwards)

Sorry i'm new to modifying 4wd's

What is the spacer for ?

Posted: **Tue Sep 23, 2003 8:38 pm**

Scott has moved his front diff forward (to improve the approach angle), by redrilling the spring perches on the front diff, the centre bolt in the spring pack then locates in the new holes. This positions the front diff further from the transfer case, causing the driveshaft to separate more than desired. The spacer takes up the slack, so the shaft won't separate when the front wheels hook over ledges when climbing. Lengthening the driveshaft is another way to overcome this (driveshaft spacer), but it all depends on what is available to you. Vibes aren't really a problem (providing you aren't competing at big speeds)

Here is a shot insitu:

Thanks Area54

So if i were to fit a 6 inch suspension lift on my cruiser i would need those spacers on the tailshaft/diff to stop the stake from seperating, correct ?

Thanks
James

Most probably not, as the suspension design (in your wagon) prevents the diff from rotating in the way that a spring over hilux (without any axle wrap prevention measures) rotates it's diffs under load. The coil sprung vehicles have better suspension link triangulation to prevent axle wrap. I'm not sure on the compression/extension rates on the driveshaft in relation to the arc of travel of the rear diff (in your 80) , but your driveshaft may not vary by many mm's during the cycle of full compression and full extension.

in a recent 75 series SOA adventure I made a spacer for the front driveshaft using 2 old front diff flanges. 63mm - 3" spacer, using an old pinion shaft nut end through the middle to allow a degree of adjustability, originally just for testing purposes but it works well so far, so it hasn't been welded up yet. weighs less than 1kg (might be more but not by much) and uses short bolts at both ends, not long bolts through, eliminates possibility of twist causing the bolts to stretch unacceptably.

fitted to the transfer end it also massively improves crossmember clearance.

EDIT: qualified weight statement - might be a bit heavier than a kg.

spacer looks phat!
ive put a 20mm spacer top and bottom and it's still not enough!

Uni joints hate my guts now!
Time for longer driveshaft and a couple of cardainal joints!

front end mods: 84 hilux
drop crossmember 2"
rear 2002 hilux springs
relocated rear mounts
diff 2" closer to the front (no drilling of perch needed)
shock hoops with 14" ranchos (they are still too short!)
clears 35's by heaps!

Cheers Chris
