front caster/pinion axle on trailtough sas swap
« on: July 07, 2012, 04:41:46 PM »
Hi,
Ive got a trail tough sas (toyota axles) lift on my 2 door tracker.  The problem i am having is maintaining my front caster and bolting on the driveshaft.  The front driveshaft is also a trail tough piece, one of their cv's.  The cv can not handle the angle that it is currently at.  What are my options? for now im going to rotate into negative caster to see how far i have to go to get the driveshaft to bolt on.... Also the driveshaft wont bolt on when at normal rest,  what happens if i hit a bump, run up a wall, or otherwise unload the front suspension,..... am i screwed?? 

I have also looked into rotating the balljoints on the front which requires cutting and rewelding.  I would like to avoid if at all possible beacuse i just spend a decent chunk of $$$ on having the axles built.. and to tear them down again would be a like a slap in the face lol... anyways Any suggestions would be greatly appreciated.

  At the top of the knuckles they are supposed to measure 6 degrees. Mine had a death wobble and I had to adjust the center link up and down 1/4 inch at a time, I marked the measurements on the frame to remember what I started at and where I went to. I finally put a steering stabilizer on it and now the wobble is manageable. I don't understand why your angles are so severe. What size tires are you running ? What springs ? yellow or blue ? I didn't want to go with a CV driveshaft on mine as the transfer case isn't made to hold the weight of the shaft. I blew one off a 98 Tracker I had and didn't want to repeat it on my 4 door.
   I'd give Brent a call and ask him what gives ? He will talk to you and help you find a solution.

the caster as it sits now is set to around 3 degrees positive.  Where it should be from factory on a toy pickup..  If i rotate forward i am going to have problems with a death wobble like you are having... the cv from trail tough only goes to 28 degrees, i measured everything out last night and i need a upper cv good for 42 fully unloaded suspension to 30 degrees normal ride height..  They make a toyota cv that can do this, but i am now wondering if there is enough room on the front of the transfer case to make it happen.. Any insight would be welcome :)
