Okay, somebody please help me out. Does anybody have any experience first hand with lowering the front steer axle on a 90's model Pete 379 by removing the blocks from the leaf springs? To make a long story short, my boyfriend did remove the blocks and still wonders why a year later the power divider internal bolts and nuts had all shook loose and 3 of them backed themselves all the way out an appereard to have been spit through the gears and chewed in half. The reason for him removing the rear end housing to discover the bolts was 3 loud bang/clunk noises we heard all with in an hour / 20 miles. He says the cause of the bolts loosening is several years of wear and tear "it's just old and shut wears out" is his argument and I say it's the extreme angle on the drive line causing a vibration that shakes the truck violently to the point that I can no longer paint my toe nails while I ride in the sleeper which he blames the rough ride on the road. Anyways, can anybody help me out here with some , anything either way so I can either shut the he'll up and paint my toenails at a stop sign while he looks soooo cool, soooo low or better yet I can paint them while we're broke down on the side of the road with @ll my told you so's.
To go low or not to go, that is the question?

I think you're right n he's wrong

No but seriously, I need more than that.
-
Why am I right?
-
Because he wrecked the angle of the driveline

An idiot friend of mine did something similar to an old Buick. Long story short, he destroyed the entire front end.of that car.
Suspension blocks are there for a reason. Suspensions are designed and set up a specific way for a reason. Yes, you can lower a vehicle and change the stance. But it takes a lot more than just yanking the blocks if you don't want major damage down the road. As far as lowering the front end of a big truck, why intha heck would you want to? Big truck is not toy, big truck is too for work to earn income, preferably the maximum amount of income for the minimum amount of expense!NWAF, tiffany42 and mountaingote Thank this. -
Mountaingote is spot on. Trucks are very sensitive to drive line changes ( they call it pitch). This is why it is so important to check the airbag height adjustment every six months or so. When you change the pitch of the drive line, you are adding additional stress to the input shaft, which connects to your ring gear. A very simplistic way to explain this is it puts the input shaft gear in a bind against the power divider. Most likely if I had to bet, he was pulling parts from the power divider.

You should work on the truck. He should paint his toe nails.

There was a thread a while back that listed some specs from Peterbilt. Try doing a search on here for "pinion" "ride height" "air leaf".
never mind. here.
