Tech Questions Here

[cajun65]

I pulled each spring off in the order that Larry said and went in the reverse to put them back on. I had to loosen the shackle some to get the front end in for the pin to go through. It all seemed lined up right, the shackle leaning just a little to the front. When I tried to put the u-bolts on though, the way I compressed the springs to bolt them down, it folded it up to the front (opposite of what that rear driver had been doing). Both folded up like that when I was done. The truck's frame never moved. In fact, I had the jack stands on blocks just to get it high enough for me to work. Then I used the floor jack to move the axle up and down as needed and a bottle jack to work the springs into place. I tried to lift the truck once it was all on but I can't jack it up enough to see if they'll fall.

Neither shackle bolt is super tight though. I think Dan might be right that it's too short now. It seems like it should work though.

I'll call later about the hi-lift. If it doesn't work, I'll be taking them off tomorrow and putting the old ones back on.

to picture your problem.......

is the shackle is now folded towards the front of the truck or rear?

i can only imagine with the shortened springs it went forward towards the front of the truck.

that is the direction it went when we first did the suspension.

it generally would be next to impossible for it too invert the other way.

that sucks marty.

i really was hopin' i was this would be a solution rather than another issue. for the 62 and the proto suspension.

wish i was on the hwy 92 LC corridor i would come by.

back mon evening.

I'm when you say "to the front". Regardless of whether or not you are talking about the rear springs or the front ones, if you say "towards the axle" or "away from the axle", it would clarify things.

Too me, if you are talking "to the front" and FRONT SPRINGS, it sounds OPPOSITE if inversion towards the axle, and to me, sounds like the springs are too long.

However, "to the front" in the rear would imply toward the axle and too short.

Just IMHO and $.02

Got into some mud Friday night, without the top on (not recommended), and found out that front tires want look in. Everything spins drive shaft, cv shafts, but not the tire. Can I rebuild the hubs, replace them, or is there something else causing this?

[cajun65]

Sorry Mike - I replaced the rear springs. The shackles are now both folded forward towards the axle all the way to the frame. When we first did the spring install, the rear driver spring folded back away from the axle. I think that spring was either bent wrong or too long. The rear driver had an almost vertical shackle angle. Tom sent me replacements saying he thought they needed to be shortened.

[third coast cruisers]

i remember unbinding the shackle and if i recall correctly it was inverted in towards the axle as well.

it would be almost impossible to get the shackle to bind out away from the axle.

it is possible but not likely.

that is why anti inversion shackles are pretty much a oneway use.

basically the direction you are experiencing.

your spring needed to be lenthened.

i will say this i still have those longer anti inversion shackles that i took off my truck you can make use of.

put the other set of springs on with these shackles and your problem will be solved for the time being.

at least untill tom figures out what to do.

[cajun65]

Thanks Dan. I'll take them (shackles) off your hand bud.

[third coast cruisers]

i am in jackson visitin with my sis.

be back mon eveningish.

we'll hook up tues.

I am not sure how that would work, seems like it would tear up Birfields whenever you try to turn.

Sounds to mee like your hubs... Never tried rebuilding a set. But I have heard you want to go back with the OEM stuff. the Warn Hubs stink for out trucks. You do have the manual locking hubs right, not the auto lockers?

I'm not sure about an '88 4runner...I'm no 4runner expert, but some models have that ADD system....it's a vacuum activation "shift on the fly" 4wd system. It's prone to working and not working mostly plugged vacuum or solenoid, etc. If you have that system, check it out. But if you had this problem, you'd probably have the light in the dash too.

Manual hubs are extremely reliable. Do you have manual locking hubs? or Auto?

[John Stw]

Yes I have the manual Asian hubs, and know they a pretty strong thats why I thought there could be something else. I guess I will tear them down and check them out first.

Sounds good bro.

[tabascoloco]

John, I was thinking that if your truck is just parked there in 2wd, you should be able to turn the axle shaft by hand no problem with the hubs unlocked.....then if you lock them, it should be totally impossible to turn the axle shafts, cause the axles would then be locked to the diff and you shouldn't be able to turn the axle.....

...just wanted to make sure that you know I'm not talking about turning the driveshaft....but rather, the Axle shaft going to the wheel...it should spin easily if unlocked in 2wd, but not at ALL locked....

Later.

X2 well said bud, also John it could be as simple as bad spring that forces the hub on the end of the axle shaft to engage.

[beyondlogic]

oh ok

thanks, im not real familar with lockers and those things.

[cajun65]

Here are some pics. Looks like my u-bolts are angled.

[third coast cruisers]

yup tooooo short.

hey when you had the other springs on the truck i can remember the shackle sitting basically straight up and down.

the optimal angle would be a angled a little away from the axle, towards the rear of the truck.

that is how the last shackle inverted when we had installed the suspension.

i will give ya call when i get back to give ya the anti inversion shackles i am not using.

[Volunteer]

Put some blocks on top of the jack and jack up the rear end under your hitch right in the center to allow your suspension to droop then take a big crowbar and try to pry the shackle back. You may need a second person on the other side and do it at the same time. Then you can see if there is any improvement in the shackle angle when the weight of the truck is on them hopefully roll the shackle to the rear when you let it down easily. If no and it flip back to where it is now take pics for Tom and put the other set back on. It appeared that as you rhode on that set they did get better.

[cajun65]

Okay, going try right now.

[cajun65]

...

[third coast cruisers]

ouch...

looks painful.

old springs back on bud you had better shackle angles.

i can even help ya when i get back.

[cajun65]

I'll probably owe Scott a new jack after this.

[PScottBx]

Just tell me you have the rig chocked.... well

[cajun65]

Very...I have Cameron leaning against the front tire.

[cajun65]

Considering my next option at the moment. If I put the old ones on, will I have to take the whole thing off again to put the anti inversions on tomorrow or can I just lift and secure the axle and then just unbolt the shackle and replace?

I've already sent Tom three emails with pics attached of the progress.

[third coast cruisers]

we can just put the shackles on without having to change out the springs.

pretty simple procedure.

Yea Dan's a pro I watched him replace his bushing during one of our night wrenching sessions before the crawl. The bushings put up a fight but Dan and 2lb mallet won.

I think I was there when he did that. Almost got you evicted, didn't it Larry? Ha ha.

[third coast cruisers]

it was a stealth install...........
