Author Topic: 5" rear leafs spring install??? (Read 3618 times)

tyes · « **on:** Jul 22, 2012, 09:50:57 AM »

I follow TG website instructions and install my 5 inch REAR leafs onto my 86 T4R. With the front spring mount 6" eye to eye from the original mount. This would be center of the hole..And for what ever reason, when i try flexing I am NOT tucking the tire like i wanted.. i end up hitting the area where the mud flaps are located. if i estimated, maybe 2-3 inch forward then the tire will tuck. That would mean moving the spring hanger 2-3 inch forward. Is my theory correct or did i do something wrong..BTW, rear shackle mount is at 2 inch from orginal mount, eye to eye.. and are 40 degree angle...shackles are previous 5inch, running on 35x12 tires.. please any thoughts would help?

i don't know if the 4" and 5" install are the same but i put the spring hanger 61/2 in forward if i remember correctly and slapped the shackle hanger right up against the original ones and bam my tires stuff perfect...

did some more measuring and took it on the same rock with a measuring tape. 4 3/8 gap from front of the tire and 4 inch gap from top of tire. the rear is again dead on the same area. i will have to move it, but not sure how far forward? 3-4 inche???

Post up some pics. 3-4 in seems like an awful lot.

have you contacted the manufacturer of your springs and asked them?

Some additional info:

ONLY leaf springs were install.
A 1/2 inch spacer was install for the drive shaft to 3rd.
Shackle Mount was move 2" inches backward.
Leaf Mount was move 6" inches forward.
Original Drive Shaft was already shorten when Duals were installed. (no changes)

It drives great and rides smooth. A little vibe from possibly the DS spacer.

I think you need to move the spring hanger forward. The angle your shackles are at now is where they should be after they settle. Once theydo settle the rear is gonna sag. Try moving the s/h forwad a half inch at a time using tackwelds. Also i don't know if the stock spring perch has the three different holes like the aftermarket ones or not but try using the rear most slot.trial n error my friend.

I like the way you think but i doubt he wants to cut this pristine runner if he dosent have to....

Measure the distance between the front of the tire and the sheet metal (when stuffed), split that measurement in half and move both the shackle and the hangar forward the same amount. then it will be centered during compression. Cake.

my math is at 2 inch if split... but, what do i do with the other 2 inch? i assume it will continue to hit.. sorry i cant picture that..

join TG and get their opinion... OR

Cut, move, "compress"

repeat till its where YOU want it

you can stuff a 35 inch tire center of the wheel well with out trimming anything. Its all about placement of the sping mounts and hangers.

you are over thinking.... to find center of something is to split it in half. To figure out where you want to place the tire, split it. bam. center

have you contacted the manufacturer of your springs and asked them?

so i called to TG and spoke with Nick or Nicholas, he was willing to help out and try to explain what could be wrong. he also mention "if followed the instructions correctly, the tire would tuck in the wheel well.. NO rubbing at all with 35s tires..." unfortunately, everything he mention about the install was done just like he mention. We tug and war somewhat about what could have happen and or what other parts not TG related can cause this not to fit.... TG suggest i cut my truck up to fit these spring.. because all 4Runner are made differently.. and all installers read instructions differently... Cutting would not be an option. it was never something to think about... but bottom line, these springs or instructions are a waste of time.. i will be posting this on TG website since they are willing to take a look. hopefully others can see what to expect when buying TG springs... this take down will be the 4th time and hoping it will be the last..

does anyone have any suggestions before i dig into this AGAIN???

The instructions are probably meant so that at ride height the tire will be centered in the wheel well. As far as rubbing you are trying to fit a 35 inch tire in hole designed for a 30 inch tire.

tyes · « **Reply #17 on:** Jul 24, 2012, 07:23:46 PM »

i totally understand 35s tire into a 30 inch wheel well.. that concept is clear.. im more concern about the 4 3/8 inch gap and a terribly rubbing issue... i understand some rubbing but, not this type of rubbing that would NOT allow me to fully use these springs..

This is very simple you have two options:

1) move axle forward

2) trim

Dirt Mover · « **Reply #19 on:** Jul 25, 2012, 07:55:36 PM »

Every time you compress the spring it gets longer (eye to eye) that is what the shackle is for. The wheel can't move forward because it is mounted to a fixed location. Slide everything forward and you'll be good to go

Rocksurfer · « **Reply #20 on:** Jul 26, 2012, 02:37:55 AM »

Looks like you may have not placed the front spring hanger far enough forward. Even though the opening is not designed to fit 35's completely (that's what bumpstops are for) your tire should not sit that far back, it should travel up and into the opening to the bumpstops.
