hi daisy i made my own crossmember which is made out of 12mmx150mmx whatever the distance is between rails. doing away with both bash plates had more tranny clearance but found my pinion flanges not within tollerance hectic vibrations all around. so i ended up buying hilux 5 degree castor wedges & put them in under spring pack which made a big differance but still a slight vibration only on decelleration so i lifted front engine mounts up with new RHS box channel fixing the problem  that was basically a 2" engine & tranny lift anymore than this will recquire the use of a double cardin joint. me thinks no more getting stuck on tranny now  |

Muvit,
Just wondering with your engine lift, does that affect the CVs?
I have no idea and I am NO EXPERT but would the engine lift actually take some stress out of the outer CVs (less angle, straighter) but maybe place more stress on the inner ones (increased angle)?
Have you had CV problems due to the engine lift as I can only imagine that you drive yours pretty hard at times,..... ;D
(Sorry or going off topic a bit here)
Cheers
Chris

Thanks for the info muvit madness il have a look this weekend, i also took your advice about going longer shackles rather than adding a leaf. they lifted the rear 50mm which only bought it up 20mm higher than the front so now looking at getting new leafs and keeping longer shackles then do the torsion bars  she must of had a big sag in the rear! |

dude the engine lift doesnt effect the angle of CVs coz there not attached to the engine in anyway  if you've already done the BJ-flip,plus shimmed the ball joint down as well as sway bar disconnects, wound your torsion bars up, cut your upper &lower bumpstops & are running 33s then next best thing is to space the diff banjo down as this will lessen the CV angle a little as i'm on number 4 CV  (but not for long) cheers muvit Muvit, Just wondering with your engine lift, does that affect the CVs?

Its drive shaft angles not cv angles that are affected. Ujoints have a limited max angle beyond which they shake Also they are sensitive to the alignment of the end shafts. If the shaft at each end is more than a degree or 2 from parellel to the other end they will vibrate. If you lift your transfer case you must lift the engine the same amount or risk a massage while you drive.
I imagine any modification of engine/trany mounts is going to require certification I would talk to a certifier before starting this project.
