I just installed my 99 4wd springs on my 2001 4wd 4runner and I am having an issue. They are the right part numbers because Evan over at Northridge made sure before he shipped them and I double checked them with the part number show in threads on Yotatech. After reading some posts on here from others who have the springs, my front measurements seem to be correct at about 36" from ground to fender. I am having worries about the rear since they are at 35". I thought with these springs installed the rear should be at least level with the front if not taller before the springs start to break in. Has anyone who installed these coils had this happened to them? I don't think I should have to put spacers to level off my suspension with brand new springs. And I also doubt that the fronts will settle that much to level it out. Are there any other mods besides just swapping the springs with the stockers that I am missing? I really need help here so I can get back with Evan to see what the next step is. Thanks

 

you probably got the wrong ones, should be level.

 

Something is obviously not right in the back.
I agree it sounds like you got the correct springs up front, the ones in back are off by a full inch.

What are the Toyota part numbers on the boxes for the rears you got?

 

I am looking at the invoice that came with the springs. The rear part numbers are 48231-35210. It may be possible that the wrong coils were placed in the box, even though the part numbers were correct on the invoice...I am sure I checked the stickers on the coils though. But there should be no modification whatsoever to get these springs to sit level on my 4runner, correct?

 

Should slide right in.

 

I thought so, but Evan was questioning me if anyone who had swaped the springs like this to a different year model were adding spacers. I didn't think anyone did, but I just wanted to be sure.

 

No spacers should be needed to get the correct ride height of 36" all around. Make sure you didn't remove the internal cone bumpers, those will make it look a little low without. Worst case you can get a set of OME 906's for the rear to finish it off if you can't get the OEM coils to work.

 

I had to get them installed at a shop because I didn't have the facilities to do the work myself. I'll have to do it in the morning, but I didn't think to check for the cone bumpers. They should be visible from behind the truck right? But if the cone bumpers weren't replaced, would that lower the rear as much as it is?

 

You should be able to see if they are there right away.

You can see them inside the coils in this pic:


The issue is I don't think that if they were left out it would be a full inch off though.

 

With my bad luck, I am not suprised with what is going on, I just don't understand why they would be a full inch too short? I will look for the bumpstops tomorrow and then I will call Northridge since they said they would warranty these out because they are too short. It is just frustrating because I had to pay labor charges twice. Once for the PP lift springs I returned and now for these. I will have to figure out a way to do the rears myself. It sucks living in an apartment.

 

I did my rears outside my dorm last year, haha.

 

You can do them yourself with a floorjack, set of jackstands and a small socket set.
No need to be paying a shop to do it for you.

 

It is a pain in an apartment but I did plenty when living in Syracuse, in the winter to boot. The worst was when I had to replace some brake lines that rotted out in January.

Little by little accumulate some tools and learn. Eventually it all adds up.

 

I wish I would have done that before I spent $300 in labor. That is for swapping 2 sets of springs, but still. Add that to the alignments and time to wait on all this stuff, and none of this has been worth it. I paid more for labor than the suspension I have on my truck is worth. I am sure some of you could understand my frustrations, but it is not over yet. Expensive life lessons!

 

Measure from the center of the hub since tire pressure and weight in the back could make the rear lower wehn measured from the ground. I just replaced my coils with a new set and mine measures just over 34" in the rear and just under 36" in the front and they've been on the truck for about a year.

I'll have to do some measurements from the hub later.

 

Your coils are sagging over 1.5" already?

 

If for some reason I can't get the 99 rear coils to work, how would the OME 906 coils work? I hear they net about 1.75 inches of lift. I have 265/75's right now and the front fender is at or a hair above 36". I was thinking the 906's with no bumpstop could be ran and I would be about .25 to .5in higher in ther rear, which would be acceptable. I am just wondering how much will the front coils (99 4wd coils) settle if any, and can I even run the 906's in the rear with no bumpstop? I am thinking if this works, this would be an interesting setup for us that want to run just enough lift to completely clear 265/75's.
