Ride Quality after Lowering
I finished up my front shackle flip yesterday. It lowered the rear about two or so inches, making the truck sit level. It looks good, though now the ride is a bit rougher than I would like.
When I first took it for a spin it didn't have the bed on it, but that is understandable to have no wright on the back and a rough ride. Putting the bed on helped some but still not as smooth as before? What would bt the next plan of attack? Remove overload springs? What about the inner load coils?
Pinion angle did not change enough to have to worry about that either which I was thankful for.

I've been in and had a few lowered vehicles in my time and they all have one thing in common. Rougher ride. The only way I know of to mitigate that is to find a lowered shock or go all out with air ride.

The S10 I used to have was about 1 inch off the ground at the lowest point and with lowered shocks and dropped spindles/coils it still rode rough. I got used to it though and miss that truck to this day. How much harsher is the ride? If all that was done was a shackle flip, I can't imagine it being much worse than factory. Mine at factory height can be a little bouncy.

Feels the same as a f350 without any weight loaded down, so not too bad. But the truck does have bad shocks which don’t help the bouncy ness. Also has the coils inside the leafs, was that factory?

I don't think the coils were factory.

Alright thanks. I will remove them.
I went for the first real drive today and noticed that at about 15 to 20 mph I get a bad vibration in the steering wheel. I think my pinion angle would be off. Where should I be measuring the angle from? Bottom of the diff okay?
and I take that value and subtract from the degrees of angle that the driveshaft is at correct?

The angle of the shaft doesn't matter, within reason, as long as both ends are on the same plane, within 2-3 degrees.

So you flipped a shackle?? Was this the front shackle? I’m wanting to lower my truck & have thought about an axle flip. My buddy has a 66’ also, that has been flipped, but they C notched the frame. Can you post pics of what you did?
I have also heard to use a magnetic angle finder on the yokes

I would say if your pinion angle is off you’re bound to have a vibration. You’re putting the driveshaft in a angle that it doesn’t want to be in binding up the U joint.
You can probably pick up that angle finder at Lowe’s, Home Depot, or Harbor Freight

I actually got an app made by Tremec for measuring this angle so I will be using it.
With bad angle it’s possible to have a vibration at either low or high speeds right? That’s what it seems like, I just want to make sure I’m chasing the right goose here. Because I don’t feel a vibration at 60 but stopped driving after j found the vibration at 15 just incase

Thanks for the help also! I’ll post back with my results once the pinion angle is fixed
