I swapped out my spiders on my 72 Chevy C-10. Symptoms were clunking or clanking when you shift into gear (automatic) indicating a bit of slop. When I took the spiders out, yeah, the gears were worn. Truck had over 200k on her but the ring n pinion were in excellent shape, hardly any wear, still smooth n no pitting. The spiders were worn but could probably still run some more. What I found besides the gears being worn is a very loose fit on the pin! The bore in the spiders were wallowed out n very loose fitting bouncing around. They could've broken at any time causing serious damage. The new set with a new pin fit nice n snug, like a wrist pin through a piston! That tightened up my ass end just right. If you really look at the diff, it's not the ring n pinion that move the vehicle. The ring n pinion turn the spider gears, the axles "fit through" the outside spiders with the splines, therefore, it's those small spider gears that move the vehicle n take the load of moving the vehicle. Those 5 lbs or so of spider gears take alot of huevo to move a two ton vehicle. So, with that being said, change the lubricant regularly with a high quality synthetic and follow the recommendations if you have a limited slip posi for lubricants, they may recommend a regular lube with a limited slip additive. Again regular servicing n inspections can save you thousands of dollars while keeping your ass-end tight. One more thing, to line up the spiders, run your hand underneath the diff with a spider gear n put one spider in front of the diff, with the window facing you, now put the other spider gear on lining it up with the bore on the front gear while sighting down the bores. If it looks lined up, it probably is, push the pin through. It should go in with little fumbling n lining up. It may be a little tricky if you have the gears pre-lubed. It's easy. No turning the axles, just line up the spiders front to back. Shifting into gear should be quieter n gear shifts will feel firm. Changing out the servo in your tranny will also give you a big boost in performance n it's a low buck upgrade that will improve shifts n add life to your tranny. Do this before you do a shift kit...

After i unstuck my throttle cable. And started driving my rear end is now making a clunk sound now matter how fast i am going can anyone tell me what the problem is. Also another thing when i am accelerating in the same truck and only happens after 80 km/h in O/D THE FRONT END SHIMM8ES AND VIBRATES and it happens on and off but when i shift into drive 8t stops all together but as soon as i shift back into OD it does it again but only accelerating after 80 kmh and happens here and there cab anyone help me out with what might be the problem on both.

Not knocking your video or mechanical skills. But, why not just go on eBay and replace the whole inside hub with a used stock or aftermarket LSD (limited slip differential)? You could have used all of your ring ,pinion gears as well as shims and clips. You would have cut your labor time in half and would have had the advantage or power going to both wheels if you’re ever stuck. And those spider gears would have never broke again. Ever. Just sayin. Either way you did a fine job and made a great video. I subscribed
@acrossmanoptimal6 жыл бұрын
I didn't want to worry about proper spacing of the ring and pinion gearing thus risking bad gear wear. I just wanted to leave everything all lined up and slip out the old spiders and in the new. An LSD would've been nice, but my son didn't need it (or want to spend the extra money) his 4WD works good enough for the snow. Parts were right around $130 total (Gears, rear cover, cover gasket, and pinion seal which we didn't replace but still have). Thanks for the comment though, I did think of it, but again lining up those ring and pinions can be really tricky, I wasn't looking for a howl or something else to cause me to re-open it. Family life has me too busy to dedicate my 'off time' as a mechanic. I squeeze these projects in when I can and my son had already gone a week without it. Hopefully he'll think next time hahaha.

@@acrossmanoptimal Oh man, I had that happen once in an all wheel drive Honda, like hitting a brick wall. Scary stuff. Mine it seems the bolt backed out, then the pin slid partway out letting the one gear loose and causing the other to shatter, luckily the pin came out with a couple light taps. Just sitting here waiting on parts. Definitely getting a full can of brake cleaner in there and good inspection before I reassemble it. Thanks again for sharing and have a great day.
Hey guys. I think my diff is a g80 m locker w/ 3.73s. Thanks maniacal s10.
He's guys. Ps my rear end came out of a '96 s10 4wd. Thanks from maniacal s10!
Hey guys. My 8.5 diff has clutch pack on each side and a rpm activevaded m locking system in my corporate 8.5. Do you guys know how to make this set up a better posi if possible. Thanks from maniacal s10.
No, sorry. I've never seen that set-up, I'm not a mechanic but I have a pretty good sense of mechanical understanding. However I love to reference Chilton manuals and other things when I'm unsure. Or I do what you just did and ask a question on a video or forum, sorry I don't have a better answer for you.
Please o please take all rings off when working on things. Google devolved by wedding bands if you think I’m crazy
De gloved “love auto correct”
I sometimes do, depending on what I'm working on, this one I should've with spinning the gears around and having my hands in there haha. I'm just so comfortable with it on I forget it's there sometimes, but you're 100% right, I should be more careful. Sometimes I'm in the middle of a Jiu Jitsu class and realize it's still on after we start rolling..oops! Thanks for the tip...to help me not lose one!
Hey guys. Grate video! You have a corporate 8.5 diff posi. I have the corporate m locker 8.5 same gears 3.73s. Is mine a posi. I did not see any clutches or other gears in the diff. From maniacal s10. Please comment.
Mike, not sure what you were referencing, but we most certainly don't have POSI. There shouldn't be any other clutches/gears in there...
Not knocking your video or mechanical skills. But, why not just go on eBay and replace the whole inside hub with a used stock or aftermarket LSD (limited slip differential)? You could have used all of your ring ,pinion gears as well as shims and clips. You would have cut your labor time in half and would have had the advantage or power going to both wheels if you’re ever stuck. And those spider gears would have never broke again. Ever. Just sayin. Either way you did a fine job and made a great video. I subscribed
I didn't want to worry about proper spacing of the ring and pinion gearing thus risking bad gear wear. I just wanted to leave everything all lined up and slip out the old spiders and in the new. An LSD would've been nice, but my son didn't need it (or want to spend the extra money) his 4WD works good enough for the snow. Parts were right around $130 total (Gears, rear cover, cover gasket, and pinion seal which we didn't replace but still have). Thanks for the comment though, I did think of it, but again lining up those ring and pinions can be really tricky, I wasn't looking for a howl or something else to cause me to re-open it. Family life has me too busy to dedicate my 'off time' as a mechanic. I squeeze these projects in when I can and my son had already gone a week without it. Hopefully he'll think next time hahaha.
I think 4wd with open diff’s is 2wd. One front, one rear.
Hey great video I hope this go easy on my 04 GMC Yukon mine Spider-gear just start messing up couple days ago I hope it go on EZ like yours
Take your time and be careful, take note of where you took things off from. The hardest part (besides all the grinding to get the pin out) was lining up the spider gears with the pin holes. Watch your fingers and give the bell a turn to help line them up, it'll be fine.
Thanks for posting this. My driver's side spider gear is torn up and this really helps. Gonna tackle the job on my tahoe soon with this new info. Thanks again.
Did you have any up/down play in the smaller gears?
stacy mccoy nothing major, I'm pretty sure they were tight. After putting in the cupped washers/shims that came with the kit underneath them they were pretty tight. Now I guess if both wheels were pulled all the way out after putting those clips back on the ends of the axles, there would be some play, but I never tried that.
Did you have to shim the gears or did I miss that? I have spider gears with lots of play that I'm about to tackle.
No extra shims or anything, just the thin shims/washers that came with the kit.
How do you fix the retaining Bolt that keeps your PIN from moving bolt broke in half and can't get it out
A new spider gear kit should come with the bolt. But if the pinion retaining bolt broke off inside the differential case (carrier), you may have to remove the whole thing to drill it out.
Hey man..nice video..but what were the symptoms that led you to replace the spiders.. Just curious to know cause I'm currently working on a 99 Suburban that could potentially have the same issues as you guys my symptoms are a clunk at acceleration speeds no shaking no grinding just clink clank.. She drives fine other than this aggravating nosie....Thank you for sharing
My son decided to do some brake stands and destroyed them. The truck acted as if it was in neutral when in drive, it wouldn't move. I had to put it in 4WD and utilize the front diff to get the truck home, what you see in the video is the first opening and discovering the destroyed gears. I'd get underneath and look for extra play in driveshaft maybe? Other than new diff fluid and maybe a gasket (if you need it), it can't hurt to open it up and take a look. Best of luck!
acrossmanoptimal ...Hey man thank you I really appreciate your response.. Thanks for the luck I'm going to need it...Stay blessed my brother..
Hey Jeremiah my 99 k1500 makes the same clink clank noise but only when I decelerate, drives perfect, but the same as mine, an annoying noise from my rear diff
Broken coffee cup symptom lol
