Yeah it does, , and in some ways defeats the purpose of the lift :lol:

I have been trying to figure this one out, because my company vehicle is a 1991 Japanese import 2.8 double cab hilux at work, i have the two to compare.

On the nissan, you think, great nothing at all hangs down below the chassis rails (you pay for it inside the cab), where as on the toyota like you say you have the transfercase crossmember hanging down lower than the chassis rails. It gives the appearence of the hilux having way more ground clearence than a Safari, but in truth, you measure from the bottom center of both crossmembers, and the safari comes out on top, but only by 15mm.
My Hilux has OME leaves and shocks and 31X10.5's
The Safari was stock on 32's.
The catch with the nissan is that although it measured slightly higher, all the sills, chassis rails, gearbox etc are at that same level approx, where as the Hilux, although the cross member hangs down, the rest of it is nice and high out of the way, and you only have one point under neath that you can get hung up on.
Its 6 and two 3's as to whats better really.
In my opinion, comparing the vehicles as standard, the hilux is better of with its low cross member, than the Nissan with the low everything.

So where was i going with this?? I've lost my self as well :lol:

Umm, yeah, because every thing on the Nissan is inside the Chassis rails, dropping the crossmember doesn't cause that much drama, its only going to hang 30mm in total lower than the rest of the chassis, and to have the rest of the vehicle up higher out of he way, its a small price to pay.
In my opinion any way.

Will get some photos when it comes back from the wheel alignment.

I know what you mean about the Toyota crossmember... I developed a crossmember for the Hilux (well, I based it loosely on the budbuilt design - new ideas are hard to find when you consider how many americans rock crawl their toyotas and have done for many years) which got things out of the way, but made the rear angle worse.

I don't have any photos (well, I do - but stuffed if I can find them :) ) but the original crossmember is 60mm thick - thats a lot. Made from folded 10mm plate instead you can save 50mm! I also have one that lifts the T/C by 25mm, so its nearly flat by comparison to the factory "horses dick"
system (by that, I mean it almost srags on the ground :P) - I run that one on my truck, its great.

Perhaps you could look at remanufacturing the crossmember in a similar way so it has better clearance even after lowering it?

double carden joint (sp??) would solve that problem i expect.
Problem there is the rear drive shaft is only about 6 or 700mm long!!!

I Have seen a few guys in the states do a 2" engine and drivetrain lift in their 'Lux's , an make a flat steel xmember that gets rid of all bits hangin down. That will of course make the driveshaft angle worse still, esp at the front dif, so ya need carden joints on both transfer case flanges and tipped up pinions.....and it alll snowballs from there, as you will need to lift the body too probably..., and ya mite as well lift the fuel tank while your at it.... new exhaust bits coz the old one wont fit anymore... :roll: :lol:

Haha, yeah thats the trouble, it all starts to snow ball!!!!
A 20mm packer is so much simpler!!!!
For the mean time any way....................

I found a decentish photo that i took while researching what was involved in this lifting buisness.
I was gathering ideas on what people had used as packers, the size, and how much vibration was felt.
It shows the transfer case crossmember and packers.

I have a mate that had 25mm packers in his Safari, and damaged his engine mounts, he was told it was due to the stress put on the by forcing everything onto angles they werent designed for.
Ended up getting custom mounts from oz, which solved the problem (he went down to 8mm packers)

Have you noticed any difference in braking?

Arrg, now your scaring me!!!!

I'm going to fire the 20mm packers in to get me Hamilton, then I'll get the UJ,s replaced while I'm up there, and see from there.
I have done some more reaserch on the the Yahoo Patrol group, and there was i guy in the UK tha tried every thing under the sun to get his vibration to go, and it turned out that even though he had replaced his UJ's he didn't have the yokes aligned properly as they hadn't supplied all the different sized Circlips with the new joints. Once he realised that he sorted it out and the vibration went.
So that got me thinking.
I can't feel any play what so ever on my UJ's, or the slip joint. But that doesn't necessarily mean they are in top form.
I rotated the drive shaft half a turn on the diff to get it running on a different phase, and that reduced the vibration again some what. So again thats an indication of the UJ's being the problem.
If i had more time i would go and pinch the drive shaft of the damaged import in town a mate of mine has, and see what that goes like. He has a huge spring lift on that which it came over with and there's no vibration to speak of.
It's just not fair!!!!!!
Bugger it, it'l survive the 800k drive to Hamilton, its only vibration, and only at 80k's, but whats it going to do to the Diff and T.Case bearings i wonder???

I did over 2000k before putting any spacers in, doesnt seem to have had an ill effect on anything.

Cheers, i was looking for a bit of reassurance on that.
Would it be possible to find out where your mate sourced those engine mounts from, that would be a usefull bit of general knowledge to have!!!!
I have emailed Mike Graham the Tough Dog guy to see if he has any other tips and tricks up his sleeve in reguard to the vibration thing.
Will let ya know on monday when he replys.
Pete. :D

He got Cheezy Racing ones, bought them through e-bay, but if you want more info, do a search here, the guy that makes them is on this site (Cheezy4x4)
http://www.outerlimits4x4.com/PHP_Modules/phpBB2/viewforum.php?f=5&sid=f83726ad3653525a39d5dd2bbd45101c

Might find more info on spacers too

Man, i can't thank you enough for that, it all finally makes sense.
I can be a bit slow for my liking at times :lol: :lol:

That info, matched with Jafa's 4x4wire link with the UJ' angle pictures i finally have my solution.

I did notice that my pinion angle had changed, but was far to focused on reducing the angle of UJ at the T.Case end.

What i really need to be doing is making the UJ angle at the diff end similar or the same as the one at the T.Case end so they are parralelle.

That would mean i could do away with the T.Case spacers almost all together. Goooood!!!!

I'm going to make enquiries in regard to adjustable or lengthend rear control arms tomorrow. Fingers crossed they are easy enough to get hold of!!!!

Thanks heaps Dave!!!!
Pete. :D

I looked at these, but decided to be cheap :)
Will have to do something better than just spacers if I go for a 3" lift though, as I'm right on the limits for the spacers I have.

Good luck in finding some.

O'dear, is it like that with those things. :roll:
I will have a yarn to Mike the Nissan magician at 4WD Concepts and see what he suggests. :D

It will be a better solution in the long run. :D

Got my 20mm spacers in, vibration all but gone, and the engine mounts don't look ti bad.
Spoke to Mike at 4wdconcepts, he reckoned i go with the adjustable top control arms as expected, plus 12mm spacers.
The control arms are $250 for the pair which is not that bad i guess.
The worst part of it is that i need to retap the captive nuts in the chassis that the cross member bolts to next time it comes off. The place that did my gear box stripped the threads on a couple, and did another one last night. They still did up tight to the right torque setting with the new longer bolts, but i suspect its the last time they will!!!
Dam it all, i have to learn how to do it. :lol: :lol:

After driving it for the 800 odd K trip up to hamilton, i decided that the vibration was far from cured.
I got on to 4wd concepts and they sent me a set of adjustable top control arms for $250.
After a bit of trial and error i got it set up and the vibration was truly gone.
So now that i'm home i can get another set of spacers made up at 10mm, and preserve my engine mounts.

The arms are great, except that one of the adjusters came loose some where betwen hamilton and wellington yesterday, and i heard it clicking as i was driving off the ferry.
A quick measure up and a re-tighten and it was all go again.
They are oh so sexy!!!!! :lol: :lol:
Shame about the big yellow primer patch on the rear quater at the moment though!! :wink: :wink:

:lol:

Edit:
I can'see any posts on my Transfercase cross emeber spacers so here are some pics of what i made:

Before i got the adjustable arm's i used 20mm packers. O made some 10mm ones when the arms showed up.

10mm versus the 20mm packer

Its finished, seems strong enough to sleep on which is good. As for doing anything else on, well that remains to be seen :wink:
