Author Topic: Pinion Angle Help!!!! (Read 5295 times)

Yotaman80 · « **on:** Oct 24, 2008, 08:33:34 PM »

I put a lift on my truck and i picked the 6 inch spring and 2 inch shackles (which i will never do again) for a total of 8 inchs. its the All Pro kit. it put it all on and noticed the pinion angle so borrowed my buddy lenghtened driveshaft and it bearly bolts up but wont turn more that a 1/4 turn. is there ant alterative to cut and turing the knuckles or i heard you can put a high pinion too. Any help would be appriciated. Thanks

get rid of the shackles on the front, thats your biggest problem

are the front hangers stock or did you get the drop front hanger?? if not you need to, this will greatly improve your pinion angle

TOO MUCH LIFT

Monster Yota · « **Reply #3 on:** Oct 24, 2008, 09:39:46 PM »

You need to run a drop hanger in the front, a HP front will help, If you ran duel cases that would help as well... It might come down to needing to do a cut and turn, but first I would do the above....

Post up some pics... Running a CV joint on your DL will help as well....

front shafts are over rated

Shackles are fine, the springs are made for a monster truck not a trail rig.....

jimbo74 · « **Reply #6 on:** Oct 25, 2008, 12:28:48 AM »

that is a huge amount of lift... thats why you are having binding issues, my friend did that on his truck.....

he is also running dual cases and also used all pro's drop front hanger as well

i think he may have a cv front shaft but i am not sure

check out his truck, do a search for thebeast8888

hey now, I won't be running one for a while either, but the welded rear should help a little

Is it the first gen in your pic, which looks to be a short bed? I'll be setting up my lift on my long bed first gen soon and am trying to fit 35s with 2-3" lift. I have a set of 87 2wd rears or top 2 leafs from a 4" marlin set. The rears will move the axle forward 2" and help me clear the body, but if I go with the marlins I'll have to get the sky axle reloacating kit to push the axle forward a little. Either way, I'll be staying fairly low and hopefully will not have the issues you are with driveline angle. Just like building a deck or patio, it's always a good idea to do your research first and account for all possibilities

GREAT excuse to purchase a dual kit and a Marlin rebuilt W56 !! Then ya won't have any pinion issues!

hammer · « **Reply #10 on:** Oct 28, 2008, 02:06:54 PM »

a cheap quick fix would be to cut yourself some extra big shims to put between the springs and spring pads. Or maybe just use two hatchet heads as shims jk......... Obviously dont go too big or you wil have steering problems
hopefully your pinion angle will improve a little after the srpings start relax
good luck....allpro has caused me problems too

Yotaman80 · « **Reply #11 on:** Oct 29, 2008, 09:38:34 PM »

dual cases and a new tranny sound like a plan to me. the cases are in the works and im waiting on some money to get a tranny. thanks for the input guys

Jud · « **Reply #12 on:** Oct 29, 2008, 09:47:32 PM »

Put a drop hanger on the front and dual cases. That should solve your problem.

Jud · « **Reply #13 on:** Oct 29, 2008, 09:49:19 PM »

Oh and if your gonna put the longer tranny in it, I have a G52 for sale here in Modesto,CA

If you don't mind me asking why did you choose to go with All Pro's biggest lift? What size tires are you planning on running? I know that they recommend running their front hanger with anything over their 4" lift kit (using 1.5" over stock shackles). Anything under you can scrape by without having to install it. If for some reason you can't do the dual cases i would say just drastically reduce the amount of lift.

jimbo74 · « **Reply #15 on:** Oct 29, 2008, 11:21:26 PM »

you sold the drop hanger that came with the kit?!

you should look into getting another front drop hanger, moving the front mount point down will help a great deal with the pinion angle

All_Set · « **Reply #16 on:** Oct 30, 2008, 10:21:56 AM »

I did a 3" Ruf up front on a 1st gen and had a terrible pinion angle. I can see why 8" doesn't work at all. I'm not sure how the 5" lifts get past this. 1st gens just have a terribly short front d-line. The longer tranny and doubler went in at the same time and I have no more pinion angle issues. (I'm not sure if just one or the other is enough for your application..)

Depending on the wheeling you do, you can chew up your stock front hanger mounts quickly. (Rock crawling is hard on junk)

Yotaman80 · « **Reply #17 on:** Oct 31, 2008, 08:10:43 PM »

yah i guess i didnt read all the install instuction and i sold the hanger a couple of weeks ago. im think about duals and a hp diff. that looks like it should work.

everyone keeps asking what size tire i plan on running is about 35s to 37s. i listen to a friend who bought the same lift and i like the way it looked. i know it over kill for those tire but the next build up ill do no more that a 4" lift. i guess you live and you learn from your mistakes.

Why would it be any different than if the hanger was on the truck?? They'd still bolt up fine.

i take it you have never done a lift be for. why would they be any different than an aftermarket one then it wouldnt work. it wouldnt line up with the perches or shackles duhhhhhhhh

um BECAUSE, the lifted springs when about halfway compressed will bind because you didnt move the front hanger forward to compensate for the longer springs

Yotaman80 · « **Reply #25 on:** Nov 12, 2008, 08:13:29 PM »

my springs have no problem with bind at all. they flex all the way til it hit the body mounts.

how would the front hanger move the springs forward when the springs are the same eye to eye as the stock ones? or i would had to relocate the front shackle hangers too.

and whats with all the haters out there.

All 3 of the trucks I have built, I welded the aftermarket spring hanger flush with the stock front crossmember and none of them have ever had binding issues.

Front drop hanger is designed to mount two ways. First is stock location of spring mount hole. Turn it around and the hole is forward from stock. This application pulls the leaf springs about 1.5 inches forward. Mounting it this way also reduces the possibility of your shackles bottoming against the body mounts. Sky's bannana shackles help cure this.

Yotaman80 · « **Reply #28 on:** Nov 14, 2008, 05:29:20 PM »

the reason they hit the body mounts was beacuse i had no shock on when i flexed it out the first time. im going to notch the body mounts anyways and gusset the else where. ivent tryed it with the shock on yet but ill will soon.

rockhound · « **Reply #29 on:** Nov 14, 2008, 06:51:34 PM »

Don't expect the shocks to act as bumpstops. You will eventually ruin them.
