Anyone have some free time to help me setup the gears in my front/rear axles? I'll have everything already torn down, just need some experience on the setup.
-
I'll be tied up for the next few weekends but after that I may have some time.
-
What's your schedule look like for the next week?
-
I never have any time on the weekend but maybe after work one day next week. What time do you get home?
-
I got the diff put in last night. Pre-load is 20-30 with as much torque as I could muster on the pinion nut, which is still less than 200lbs. Backlash is .07, and the pattern looks shallow on the drive side, deep on the coast side, and perfect where the paint rubbed off on other teeth.
Pattern looks like the bottom left of the acceptable patterns picture.

I get home around 6.

Good work man, i bet that pattern wil be fine.
I have so much to do to our camper in the next two weeks to get ready for our vacation that i don't know if I'll have any time to help with the other diff but if you get in a real jam let me know.
-
will do, thanks!
-
I thought I had an open 9" carrier, turned out to be a trac-loc. Anyone have an open carrier sitting on the shelf?

-
Got the front diff installed. Not a pro job, but i'm betting on it holding together. Either going to regear my trac-loc or hopefully find an open carrier so I can go ahead and do the spartan.
-
If you're going to use it mostly off road hold out and put in the Spartin. If it will be mostly street the trac-loc will be much better. An automatic locker can be quirky on the street. I have mostly gotten used to my Grizzly but it can be a pain sometimes on the street.

good news is if I don't like the spartan, or if I blow it up, I'm not out much. If I go LSD, it will be true-trac

What are you going to do with the 3.50 9" gears you pull out? I need to re gear the rear on mine it is a 3.00
-
you can have them. I'll let you know when I get them pulled
-
ok thanks
-
I never bothered to count the teeth on my 9" 4.11 gear, since 410 is clearly stamped on the ring. After chasing a binding issue, discovering that the rear tires completed a rotation faster than the front, and finally counting the teeth, my rear gear turned out to be 3.50. So, now I have a 4.11 richmond set on order.
-
Well that really sucks.
-
new gears and brake stuff ordered. will finish the setup next week.
-
Did you get your gears finished?
-
I did get this finished. gears and lockers installed. Rear setup without needing any different pinion shims than what I already had. Pattern looked good, slapped it back together and off I went. Went on a trail ride with Scott(RedTinTop) the saturday before thanksgiving. VERY dry and dusty, though we did find a fair amount of mud. He was impressed at what I managed to get through, and I only got stuck when the axles grounded. He fully expected me to need a pull more often since I am running ATs. The only time it wanted to plow in a turn was when I was full lock in some slick stuff, other than that, it drove pretty normal. Still tweaking the steering a little bit, and now I've got rear brakes to replace.
-
That's awesome, it does make a ton of difference with both ends locked.
-
ended up with a nasty vibration at 65mph. Determined to be the splines on the rear driveshaft had 1/16 - 1/8" deflection...not good...got a new driveshaft ordered from wildhorses, including u-joints, for $300 to my door. Should get things running a little bit better.
-
A wore out driveshaft will certainly cause a high frequency vibration, hopefully that will take care of the issue.
-
should be here monday. after it had shipped, I realized that a tom woods shaft would have been cheaper. WH may be reselling TW, so I may have simply paid an extra $30 to get the same thing.
-
Yeah, i wish i would have known you needed one before you ordered. Tom is a great guy and builds the best shafts around. Can't beat his prices, fast service and warranty either.
-
it is a Tom Woods shaft. Looks like I got to pay $30 for the privilege of buying from wildhorses. oh well, got a good product for sure though.
-
The best I've found.
-
driveshaft did not fix the 60mph vibration, though it definitely smoothed out the sub 60mph driving. Going to check my pinion angle next. It occurred to me that I may not have ever taken it over 60mph before doing the gears.
-
got it sorted out. the front hubs were still locked in and the front pinion angle isn't ideal. unlocked the hubs and vibration is gone. between that and the new shocks, it is like a completely different animal.
-
Isn't it nice to have an easy to fix problem for a change. ;)
