I just went out and looked at mine in response to your post. I have the 5.5” Superflex with the J40s out back. Here is my spring perch with what looks almost like the stock wedge angle, with the fat side forward (forward is to the right in this pic). The springs have an angle built into them, but going with no shims would point the pinion to far upward I think, looking at this.
as far as axle wrap,
You might be surprised just how much flex their really is when your climbing.
I seen a guys rear tire actually moving so much it was binding up on his rock sliders.
(although he was "Block Lifted")
The best solution is a new set of perches welded on with the axle re-clocked to get the pinon angle correct on YOUR truck with stuff you plan on putting in it. This is just one of those things that is not a 1 size fits all to get it 100% correct.
I also agree on the antiwrap device, however if you go the new perch route, picking ones that are longer then stock, and thicker metal will help with that too.
There is a small gap between the leaf spring and the wedge, when I brake hard and or hit the throttle it makes a "clack" sound. I'll need to remove it again, I didn't notice it until I heard that noise on the way to the alignment shop and visually inspecting there.
So the PO of my 78 decided to jerry rig gator connections to the tailgate to use a battery pack to raise/lower the glass. Needless to say this has become very annoying to use and would like to diagnose/unscrew the whole thing and fix it properly. So the dash switch and the tailgate keyhole dont...
Good morning All! I have read a few threads on this issue and am trying to confirm some information about the neutral safety switch. My bronc will not start when I turn the key. I have no power to the wire that goes to the solenoid. My battery appears to have almost 14 amps when the truck is...
This relay "Clicks" when I hit the key and I think is in the key to selenoid circuit as the engine wont crank with the key but if I jump the selenoid, it cranks/starts. The Fors PN comes up as a 78 T Bird top relay but I I can't find one on ebay/NAPA etc. The Ford PN is
Good morning All, I drained my transmission fluid as instructed to do from Mieske and other helpful folks! My first time, yeah! It was primarily all a light tan color. If you remember the 82 sat outside for over 20 years but was in good working condition before being parked. I never had a...
I need some input to see if I did this correctly and if my assessment is correct.
So I recently had to take apart and put back together my cylinder lock. I made sure the key was in the RUN position when I put it back in and that the actuator was fully forward (towards the fire wall). When I...
