So with the help of my good friend cruiserbrett we did a major overhaul of my FJ40 a year and a half back. When we did the cut and turn I used stock springs front and rear. Over the past year they have settled quite a bit in the front and rear. I was getting some vibration on the rear dshaft when the rear end was loaded up with camping gear, etc. I used a long add a leaf from man a fre to solve this and it worked quite well. Now no problems with the rear. The front however has settled quite a bit now and I have noticed that the front pinion is angled up too much, maybe a few degrees. It has not been a major issue, the only symptom is when I am driving in high 4wheel drive I will get some vibration above about 25 miles per hour. I mainly am doing slow rockcrawling so not a huge issue but I would like to set the angle better if I can. The other issue is that the front driveshaft is hitting the bellhousing (see pic). I think if I could turn the pinion down a little this would not happen as much. The bumpstops I have will keep it from grinding too hard on the bellhousing too much. I have grinded some metal away from the bellhousing and plan to grind some more off where the dshaft is hitting (shiny metal).
I am trying to figure out the best way to remedy the above issue. I REALLY don't want to pull the axle and recut and turn. The pinion angle was not like this right after the rebuild and SOA was done which leads me to believe that if I added a leaf in the front spring packs it may remedy the situation by lifting the transfer case a little and straightening out the dshaft angle. I have also thought of lengthening the shackle length to increase the lift as well, or buying some new aftermarket stock height spring packs from an aftermarket vendor. What I am looking for is opinions on 1 - is the issue I am having going to cause major problems down the line if I leave it at the angle, ie: shot ujoints, pinion breakage, etc? AND 2 - opinions from others on what I can do to remedy this hopefully from people who have had similar SOA cut and turn issues. Any and all comments appreciated!
