So today me and a buddy put on a 4" suspension lift on my 77 short box. Looks real good but the passenger side is sagging a bit, by about and inch or so. Anybody got any ideas why its like this? I was thinking because new shocks, springs, bushings, etc, but would that make it sag down?





Little dirty but still looking good!

 

Try rotating the coil up front and see if that helps i know it did on my Jeep a few years ago.

 

Did you put new C-bushings on the radius arms? I've heard stories of people putting them in wrong and putting the front suspension in a bind.

 

Agree with the above happened to me just the right on of the c bushings was wrong I think front and it was like a little over an inch or difference. Wouldnt hurt to check that fronts are fronts and rears are rear.

 

It looks as the front driverside is sitting the highest of all and maybe that is why the left rear is sitting lowest. Another thing to tackle for the upcoming weekend. Thanks for the help guys!

 

This may not be the problem on 4" lifts, you may need an adjustable track bar.

 

The front springs' last coil (the bit end) should extend about 1.5 inches beyond the strap that bolts to the spring bucket. It'd be tough to install it any other way cuz them straps are short. Second, check how the coils seats on the coil cups bolted to the axle. Sometimes thicker coil windings (higher rate) barely fit into the cup. Is it resting on the rim of the cup?

Diagnosis: Park your rig on a flat, preferably concrete, surface and measure the same points side to side and determine which corners are up and down. That should at least identify which corners are affected. Now ya gotta figure out which one

Btw, did you do final torque with the vehicle suspension loaded? I mean, ya could have literally introduced a "bind" and the bolt/nut/bushing can't unbind and rest naturally.

The track bar (too short with a lift, typically) would likely pull the cab over towards the passenger side and make the rig look like its crabbing down the road. I don't think that's the issue but a head-on view of the rig can easily reveal if it is.

Sometimes a couple of hundred miles will work the bushings and settle the springs. Let us know what you find.. we'd be interested to file that caveat in our overflowing fountain of knowledge.

 

It came with a new track bar that we put in, but maybe to short? But i didnt convert my Y steering to T steering yet, could that maybe be the reason? Ill park and make some notes and let you guys know more on whats going on

 

I haven't converted my 'Y' to a 'T' yet (5.5" lift), mine doesn't lean so I don't think that's the problem. You said that the bar maybe too short. Did you adjust it?

 

yah we'll take a closer look at it this weekend

 

Sorry for being off topic. What size wheels and tires are on your truck. I just put a 4inch lift on mine and lookin at getting new tires and wheels. thanks for the info and good lookin truck!

 

There 35 x 13.5 tires on a cheap 15" wheels
So i left it flexed out for a while this weekend and the lean went away! Well, its leaning a little bit but not as much. Still gonna switch around the coils and play around with it but for the most part its looking good again!

 

I'd almost bet you had some of the bushings in a bind and now they have settled. Have you driven it yet? It may settle right into place with a few more miles if thats the issue.

 

Yeah i was driving it today, it still leans a bit but not like it was, gonna try switching the coils around tomorrow but for the most part is riding good now
