Drop question? 1 inch down on left compared to the right ?

My left front side drop is about 1 inch roughly lower than the front right side.

I've measured this at different locations to make sure it was just a hair higher elevation in the parkin lot then or over there etc. and the same distance is there.

What do you think the problem is guys?

(there's no weight in the bed over balancing on one side either)

Thanks for your time guys!

The infamous Chevy lean. Forty years on the road and the frame is probably tweaked a bit.

Re: Drop question? 1 inch down on left compared to the right ?

Did you measure the ride height first?
From the ground or the center of the wheel to a repeatable fender lip?
Did you verify the free height of the new springs as being equal between left and right?
Are your cab mounts good? Lowering could have made a pre existing condition more noticable. Is the frame known to be square?

Re: Drop question? 1 inch down on left compared to the right ?

This happened to me as well, in my case a spring had sagged. Measure in two places like the centre of the wheel wells and a frame location - pick bolt holes for reference and make sure you are on flat ground.

Re: Drop question? 1 inch down on left compared to the right ?

Take a look at the cab supports and mounts. Left side usually wears out before the right, especially if the PO was a big guy...Might take a look at the core support mounts as well.

Re: Drop question? 1 inch down on left compared to the right ?

Oh wow! Awesome guys!

The measuring tips will be on my To-List for tomorrow!
...i'm excited to see what the measurements are because all the cab supports from being under it a numerous amount of times are still good. But hey, there's no problem with checking again!
Thanks so much guys!

Thumbs up Re: Drop question? 1 inch down on left compared to the right ?

I agree with the frame sag. I have built five trucks and everyone of them had the probem. I do body work so I have access to a frame machine to bring the frame back to specs. If you don't want to go to that much trouble, you can get a spring rubber that goes under the spring to raise the corner. I think O;reillys, or Advance auot parts has them.

Re: Drop question? 1 inch down on left compared to the right ?

Hey, I've only got maybeee 500 miles on the drop. So the springs should be good to go if that's what you were wonderin.
I'm thinking a spacer probably in the front...will see!

Whatever you do, carefully consider exactly what is causing this and do everything possible to correct only the root cause and if you decide to alter something else to compensate think real hard about that.

Put it on nice level concrete and start measuring. If the springs are the problem, then you should be able to detect a difference from side to side from the bottom of the frame to the pavement. If the frame is level on the front, then it's probably something else.

That being said, if it is springs, aforementioned spring spacers are the best way to go.

Also, consider the condition of the a-arm bushings. Worn, stiff bushings can alter ride height. Maybe get out the grease gun.

Re: Drop question? 1 inch down on left compared to the right ?

Hey!
Yeah I will deffently keep that in mind: What happens here could move something over there.
And I haven't measured the frame or body in certain places, but that's on the to-do list for here soon!
I'm having a feeling, a spacer(s) is probably gonna be the fix.
Will see I guess!
Thanks for your time!!

Re: Drop question? 1 inch down on left compared to the right ?

Here's the measurement from the center cap on the front wheels......

I also measured the frame front and back and it's all really close for being 45 years old! lol

.....What do you think guys? Would it be stupid to put only one spacer in the front to level it out??

Good ideas guys??

Tyler, by looking at your two pics, you have a good 1/2 inch difference from your measuring point and your rim edge... one is shy of 12 inches and other is strong of 12 1/2 inches.

Re: Drop question? 1 inch down on left compared to the right ?

Sorry the photos didn't rotate correctly. And yes the photos are tough to tell exactly the difference, but were looking about an INCH down on one side than the other......

Re: Drop question? 1 inch down on left compared to the right ?

Mine sat uneven when I got it. 1" down on the front drivers side corner. Thought it was just tired parts. Changed out all the suspension (springs, shocks) etc... New cab mounts, new rad support mounts.... Still leaned.

Took it to a frame shop and had everything squared back up,and set to factory zero. Still leaned. The body panels and body lines are perfect so we agreed the frame is indeed straight.

So I said "f*ckit" and cut my passenger side (brand new) coil spring down to match and level it. Perfect.

But now, a few months later, my passenger side is too low.

I give up.

Re: Drop question? 1 inch down on left compared to the right ?

Mine leans to the drivers side about an inch as well. It made me think the frame was twisted. Crawling around under the truck one day I noticed the core support mount on the drivers side was completely gone... metal on metal... that makes up the 1" difference in the fender lip and also why the bumper looks tweaked... bumper is fine its the gill that's low. New mounts should get everything lined up.

Re: Drop question? 1 inch down on left compared to the right ?

Well according to your tape, your only a 1/2" inch down...That phantom can be spread out in 40+ years of existence...It's an old truck, not an Acura...A 1/2" can be in the body panels, sag in the cab supports and sheet metal...It can be in the new springs, have you swapped them? It can be anywhere, and everywhere..."just sayin" PS...When you get it right, it's going to be down again as soon as you get in the truck...

Hey! Thanks for writing on here for me...and yea; AGE is probably where its at. lol And to answer your question: Yea I've put the new drop springs in, so there new. And the body mounts seem good to go! So I'd say...it's just the years on the body all the way around I'd guess! lol

Re: Drop question? 1 inch down on left compared to the right ?

Have you measured the difference in spread between the spring seat and upper AFrame? That is how I found a spring problem on mine years ago.

Spring was lifting one side more than the other. it was 3/4" difference which made a difference on the truck that was visible.

wouldn't new springs eliminate that?
