BLAZN BOSS

little over 1/2 inch..........350 ftlb???????????? sure it isnt NM? The max torque for a 14mm bolt grade 12.9 is 158 ftlb an 18 mm is closer to 350 but thats about a 3/4 dia bolt.

I did mine on jack stands, was a pretty tough job. I had to buy a Titanium Impact gun at almost $250.00 just to remove the jolts.
I scratched up bottom of floor boards and a few weeks later had to go to O6MACH1S house and use lift to tighten things up.
 
Honestly, I paid 150 to have it done. Took 5 hours, removing the driveshaft(dss) to measure and adjust pinion angle.

Got back under the car today to make sure that everything was tight and then had a chance to beat on it for a while. Rear grip definitely seems improved and the car seems to hook up in a straight line even better than it did already w/Steeda billet LCAS, Whiteline relos, J&M panhard, and P springs. I also installed a Drake panhard brace along with the UCA last weekend. Traction coming hard out of 2nd gear corners seems amazing - it doesn't seem to need quite as much delicacy with the throttle as you pass the apex.

Only downside so far is some differential whine at about 75-80 (goes away above or below) and also some additional sort of 'feedback' on shifts. It's not really a clunk, but you just hear more noise coming from the driveshaft I'm guessing. I double checked pinion angle today so I don't think that is the issue. It's probably just something I will have to get used to.

When I tried to do it on jack stands I gave up but when I got the car up on the lift it was a breeze. Long extensions and impact tools makes the job easy. I have taken my Steeda UCA and relocations bracket in and out at least 5 times. Took a while to get everything lined up so that I could set the pinion angle properly and ensure everything had the proper clearance. I had to pull Bob's axle reservoir though because it was contacting on the UCA on the recessed portion of the reservoir where I thought it was supposed to clear when the suspension compresses. I'm going to have to fiddle with it to make it work. It hits on the bolt so maybe I just need to flip the bolt around? I'll take another look at it this week. I torqued everything to 129lbs. My UCA is spherical so I get more noise from the rear but it's not too bad. I'm going to double check the pinion angle again also, I set it at -2.
