hey guys, i am currently working on my 92 pickup which i have swapped in both front and rear axles from a 79 truck. i put the 51" springs from the rear up front and have the chevy 63's in back. 5.5" eye to eye shackles up front and 6" in the back. all the shackles are within a degree or two of each other (at about 18 degrees. the problem i now have it the passenger side of the truck is sitting higher than the drivers. measuring from the ground the the bottom of the frame there is about a 1 1/4" difference from sided to side in the rear and about a 1/2" difference from side to side up front. keep in mind the truck is pretty much bare, no drivetrain or anything in it. im not sure whats making it side higher on one side. hope i gave enough info, any help would be awesome!! thnx!!!

 

Did you install a spring perch spacer on the front axle, driver's side perch?

If not, that may be part of the problem as the passenger side perch is taller since it sits on the side of the differential section. With equally arched (i.e. non-stock) springs, you need the spacer to even out the height and that can make a big difference and that difference up front can look even bigger in back since the front end has more weight/stiffer springs than the rear, so a little off up front means a lot off in back.

And there will be more weight on the passenger side as you put things back, the battery lives on that side, the front drive section of transfer case and front drive shaft is on the side as is the gas tank.

 

ok thats my issue then, i guess i didnt know the perches were different. thanx a lot!

 

well, quick made myself a 3/8" spacer for the drivers side perch, but it didn't help. the drivers front still sits very noticably lower than the rest of the truck. i also tried swapping the front springs from one side to the other and got no change. at the front of the truck its about a 1 1/4" difference from side to side. im now out of ideas and dont know what to do. any help would be greatly appreciated!! thnx

 

Post pics. Are you a big dude?
And I would have left the rear axle from your 92 and just run spacers up front.
Did you trust the front axle? 79-80 isn't a strong front housing..

 

Did you compare the two front springs side by side when you swapped them? Did they have the same arch and the same number and thickness of leaves? Also, what about swapping the rear springs side to side. Is this still on a stripped down chassis?

Might also try taking careful measurements of ground up to things like the spring perches, spring hangers, shackles, frame, etc. to see if you can find anything that is off. Like is the driver's side spring sitting flatter than the passenger side?

 

no, im not a big guy...average. i knew the 79 axles are a bit weaker, but they should work for what i want to do. when i swapped the springs i laid them side by side on the ground first and they seemed to be the same. the truck now has a 350/nv4500/Tcase installed in it, but it was unlevel before the drivetrain was installed. the springs are just the stock rear springs minus the overloads. i know it needs more leaves added, and i have some on the way, but if they"re already off, wont it still be off when i add more leaves?? i snapped a few pics, if you need/want more pics of something specific just shout.

Well, unless something is bent and swapping springs did nothing, then there may be more weight on the driver's side as the chassis not sits. Could always add one more leaf on the low side and see if you can level it out. And it could be the passenger rear spring is sitting taller and pushing down on the driver's front, sort of like a teeter totter.

 

tomorrow i will try swapping the rear springs and see what happens

why in the world would you swap a '79 rear into a third gen truck?! if its for gears, just swap thirds. That IFS rear axle is both stronger and wider than the 1st gens. now you have to run at least 1.5" spacers in both the front and rear to match the axles to the truck.

 

yea i woulda left the rear axle, no sense popping in the one you did.

Looks like youre running on bumpstops upfront? Those springs almost look inverted, passed flat. Hard to tell from the pics.

Thats a big motor to run over RUF's... I'd reconsider your spring choice.

FYI my rig leans driver.. springs are like women, never two the same, always finicky, never settle right

 

i tried swapping the rear springs and it didnt change anything. i guess ill just have to add more leaves to that side. i know the 350 is pretty heavy, not to mention the trans. i dont have any bump stops on the rig right now, and yes the springs are flat in not slightly inverted. should be getting another set of springs this weekend and with any luck i can combine the two sets and lift back up. i guess the reason i used the 79 rear was to have matching axles, i'd planned on wider wheels and tires so i wasnt even going to run spacers. of coarse i found out shortly after that the 3rd gen was better(im knew to this toyota stuff). are there many other guys running ruf with small blocks? i guess ive seen so many 350 powered yota's and a lot of ruf setups that i figured it was fairly common that some one would do both....

 

You'll need at least two sets of stock rears for that engine. I used 2 for my stock 22RE:

And probably not worth worrying about the ride height/levelness until you sort out the springs up front. If they are sitting flat or inverted, they are overloaded and you are basically looking at what the spring look like fully compressed. Get a bit or arch into them at rest and see what it looks like. Just keep adding leaves until you get the spring looking good. I started at 5 leaves then went to 6 and finally 7 before mine got working right.
