remove skid plate then simply unscrew the two front diff. mounting bolts and allow it to drop 1 inch, the bolts are very long and will not come completely out. the spacers go in the gap you just created at the frame ,now look at the CV angle. thats all the kit does. does not do anything to steering or any other component as others like to to think.also take note at the U joint angle from the driveline. There is a 1/4 inch spacer that comes with kit also for the skid plate, it does not alter the clearance since the plate is slopped..the rear mount is not changed..its very simple and there is simply no disadvantage from minimizing the CV angle. As mentioned earlier it corrects about 1/2 of the angle created from raising.

 

just the front huh?.
Ill have another look. it would change only the driveshaft angle then. that's ok?

 

yes do the test and loosen the bolts, takes seconds. the bolts are very long and you re- use stock bolts even with the spacer kit.

 

The drive shaft angle change should'nt be a big concern, since the rancho lift uses a drop bracket that drops it 3" I believe (but apparently thats too much for the drive shafts CV boot).

Now why is doing the spacer thing bad?

 

Theres nothing bad and no downside, There seems to be a following of individuals who are internet mechanics and have trashed everything ive said. Fact is they dont even understand whats taking place in the spacers.comments such as it wont possibly fit, or you will lose your ground clearance-or the it will screw up the steering and put extreme forces on other components which all all BS, It simply helps correct the effects from raising to 23.5 -24 inch and lessens the CV angle for under 40 bucks. as far as the driveshaft its fairly straight and no issues at all. its even straighter than the rear driveshaft in stock form .I come to this web site to learn from others and others can learn from my findings. A small few destroy the willingness to even respond on this website as they think they know all. Such as Tainters arrogant post,

 

I think I have it. you are lowering the front,rotating down and the rear would actually go up huh?
the weather is messy here and I didn't go under again. im just interested in new approaches and I check out a lot of stuff because ive seen a lot of "made up" stuff over the few years ive been here. some needs challenging!.
yours sounds good. I just couldn't see the clearance. confirm the rotation thing huh? ill get a better look on my next oil change.

 

Yep thats correct.that describes it well,,

 

Well I've just done more reading and got responses from members with more knowledge on this issue. The increase in drive shaft angle results in ripping of the CV boot (which is apparently crap and extremely sensitive) which eventually requires changing the entire drive shaft. In addition, the combination of a tilted diff and a worn out CM bushing can put more stress on the diff resulting in damage to it.

 

Byeatts are you thick headed? Am I special? Listen moron, I am a certified mech and if you read a tad bit closer maybe you will see I "supported" what you were saying, just reminding that a lot of "engineers" at GM spent some time on the front suspension. If you read a bit harder you may see I also said a few of the "senior members" just want to knock the "new" and "not their" ideas. And just an FYI I am "special" my mom tells me eceryday! Oh, and take a look at a 4wheel parts mag and check out what is standard with the Toyota leveling kit. Ya, diff spacers. So mr. I went to school to learn to use calipers and tape measures, take the time to read something so next time you don't come after someone supporting your theory!

 

the cross member at the rear Diff mount remains untouched, The front two diff mounting bolts drop one inch.and theres an included shim for the front skid plate mount if thats where you concerned about the 3/8 inch clearance..
