    So after some testing on the t-case i will be able to use the twin stick shifter with some modification over the transfert case and on the arm too.

    So i will move forward the pivot bracket about 2-3 inch and i will shorted the threaded rod between the tie rod end. I will need to bend the stick a little to the rear but it will work for sure.

    Not the best thing but i don't have time to wait 2-3 weeks for the right stuff to get in.

    So this weedend is tranfest case project, rear shift rail modification to allow front wheel only and reassemble of the whole thing and try to get it back on the jeep :)

    So this week-end was very productive. Tear down two t-case so i can built one good. The use of the tapered bearing kit made the assembly pretty easy.

    I work on the twin shifter and i decide to modify the shift rail instead of taking off the interlock pin.
    In my mind the best way is to go with the modified shift rail because this you cannot engage the front in high and rear in low, that why you need the interlock pin.

    So on the side of the rear shift rail i just grind up some material to allow front and rear independant operation but still keeping the safety of a high/low engage. Upper one is Oem and bottom the one with the modified surface.
    18493319_10154305855736621_2102001104_o.jpg

    Also there is a another modification to be done, you need to clear the ramp for the rear shift rail where the ball spring lock the rear in low. They made the ramp for easier operation when coming from 4wd lock to neutral. But i'm my case since is independant i wanted a strong hold so i put some weld along some grinding. If you don't do that you may have problem with the rear to pop out of gear.

    Upper rail is the modified one and the bottom is the oem.

    Finally i did move the pivot bracket for the shifters, move it about 3 inch forward, it now work pretty good.

    So everything is ready to go back into the jeep

    So had time to work on the jeep yesterday.

    Twin stick shifter is finish and it look like that.

    Finally no bent just cut a little into the fiberglass body.

    You can see the castle nut for bearing ajustment from the tapered bearing kit for the intermediate gear.

    Almost finish my spring list :) still some modification to do but i can take it out for a ride

    18789555_10154353132916621_1316747603_o.jpg

    Did an align yesterday and take it out for a test drive. Still need to work on the align tonight i'm not satisfied yet.

    First impression on the toyo open country, i like them, pretty quiet, pretty smooth, way different than my tsl's. Still have some test to do over tire pressure to find the best for road manners :)

    Chrome wheel make a drastic change over the look but i like that.

    So i drop the suspension, jeep was not level.

    So i drop the rear around 1.5" using another set of coil spring i have and i drop the front about 3/4" removing a spacer i put between coil and coil bucket.

    So before
    18870080_10154355419831621_321798210_o.jpg

    And after

    rsz_img_3956.jpg


    Don't seem to be a big difference but i like how it sit into the fender.

    I give a test drive with the toyo tire and they are day and night if you look over my Tsl's. Also i don't anymore vibration that i use to have with tsl at 50 mph. Not it run smooth at every speed.


    Now i have to work after my alignment, i may have set to much toe in, my jeep wanders left to right and steering wheel doesn't center pretty well. I did put 1/8" of toe in but i use my front disk brake to do it. I read yesterday that you need 1/16" to 1/8" toe with the tire so you have to take mesure using the overall diameter of the tire. So my method is bad and a may have too much toe in.

    Looks good.
    I am still chasing my alignment as well. I read a long time ago to do this method.
    Raise the wheels off the ground. Mark a chalk line all around the tire on each side. I marked mine on the inside lugs. Lower back down and roll forward and back to flatten out the suspension. Use a string to check measure at the rear and the front. Someone may have a better method.
    I messed with mine again on Weds but have not had a chance to drive it yet.

    I will make some try and error, i will do some road test with different toe-in ajustment in hopping to find the sweet spot.

    I know my caster is good around 6 degree so it only the toe-in that give me headaches.

    So i work over the alignment this week-end and i'm not able to set the toe-in where i want it to.

    I have try this method using 4 foot level.

    AlignmentCombinedVertical.jpg

    So the toe i try last week was bad, both tire were perfect parallel. I try to give between 1/16 and 1/8 of toe in but with my ram assist bracket that is weld on the tie rod i'm getting parallel of 1/4" of toe in. Since my bracket is welded i'm not able to ajust the toe as i like too.

    18789555_10154353132916621_1316747603_o.jpg

    I did seem before some picture with a clamp for the tie rod to use with the ram assist. This product make alignment an easy task. Psc make one and i'm lookin to get one asap.

    On another subject i had the chance to try my new upgrade over the jeep.

    I'm city there is an abandonned district that has been moved out 40 year ago (200 house) due to a surface mine getting closer to it, so it become dangerous for the people to live there. Funny thing is that mine get bankcrupt couple of year after the big moving.

    This place over time became the playground for ATV, motocross, 4x4 and other, but there is stupid people that think they can come and discharge garbage all over the place. There was a cleaning day yesterday to get rid of the garbage so i decided to make a good action and put my hand to the task. It was a good test drive along that.

    18987387_10154367967696621_606728538_o.jpg

    So we fulfill four container of all kind of thrash.

    On other hand i can say i love the new feature on my jeep. The twin stick on my dana 20 work as a charm, easy engaged/disengae, tapered bearing kit in the dana 20 make it very quiet. Didn't have chance to realy test out the rcv axle.

    Keep in mind, toe-in specs are a set to a degree setting; typically .2 degrees. To convert to an "inch" measurement at the tread, the bigger the tire, the more the toe-in you will have at the tread. With 36" tires, your 1/4" measurement might be right where you want it.

    Did find a website Convert Toe Inches to Degrees

    With 35" tire and a total of 1/4" toe in i got a .4 degree, if the website calculation are right.

    toe .25.png

    So i'm away from the .2 degree. The good toe in for a 35" is still 1/8" for a .2 degree

    You may want to at least try the "chalk/string" method I mention above. It involves a lot of crawling around under your Jeep but it has always worked for me. One of the critical steps is rolling it a few feet back and forth between adjustments. It took me a while to finally get it right and I think it may still need a little fine tuning.

    So receive the tie rod clamp yesterday. It's a nice piece of work.

    19048655_10154380031351621_831753613_o.jpg


    Yesterday i was looking on the steering component on my jeep and i think i will need to change the ram assist location. With the clamp when it will compress both side of suspension i'm afraid that tie rod and drak link will touch each other.

    The only location i found for the moment is to weld a braket over my diff cover (1/4" thick metal). More to come....

    Pretty hard to convert toe inches to degrees without having the proper equipment...............like a set of turning plates. These are great to have even if your setting your steering up with a tape measure..........I have an old set somewhere that I got from an alignment shop that went out of business somewhere that looks like these.................allows for the vehicle to be put on level ground and cycle the steering to check toe after each adjustment.

    Now I'm not saying you need to do this as the method that Jeff described above works pretty well as I have done the same many times in the past..............

    Although I like to first jack up the vehicle on each side and while a friend is spinning the wheel and tire , use a large piece of that kids colored driveway chalk and chalk a wide center line and then while the wheel & tire is still in motion take an ice pick or other sharp pointed scribe and while holding it steady up against a block of wood with a groove in it scribe a fine line inside the chalk area...............much easier now to see the center line fore & aft and much easier to get exact measurements.

    Also prior to me having turning plates I used to take four metal plates of equal size and put a big glob of grease between each pair and stick those under each front tire on level ground............home made turning plates.

    Having this tool would be great.

    But i'm questionning myself about the method you had describe. I was thinking that going direct on the disq brake using two foor foot level with some mark to get the right tire diameter would be the best.

    Taking mesurement on the tire in my mind could give you bad reading because you have too much element that can false the reading. Tire/rim may be not fully centered that why i was thinking that disq would be better.

    But that's in my head, i'm no expert but my logic i would think the disq over tire.

    The tire properly marked on the ground or better yet on a turning plate..........loaded with caster & camber on it's axis is what see's the road , the disc has it's own inherent issues with trying to get around each side to take a measurement..........The method I described above is what tire shops have used for years to set toe-in.......although they used to also have a motorized wheel that when pushed against the tire does the turning.

    Now they do the toe-in and alignment with lasers .............with the measurements starting off the rear axle............Good Luck!

    So i installed the clamp. I did set to toe-in to 1/8". It made some difference (positiv) on the handling. You can see the clamp on the picture. I will try to take one closer.

    This week-end was very warn in temperature so i did some mileage.

    rsz_img_4017.jpg

    Also i was having little missfire under load on my engine this week-end. It got worst yesterday as it was very warn outside combined to a high humidity. I'M running a large cap delco distributor, i did have a coil, cap and rotor in spare so i switch them and the problem seem to be gone.
