according to my dad if i was running a welded rear and drove to uwharrie national forest (2 hours) i would have to let my truck sit and wait to wheel? i really want some sort of locker in my truck but being a broke ass teenager doesnt help much. i have never heard this from anyone but he seems to think "everyone" says it. if it true than im dumb but i dont think so.

i have no idea why...i drive mine on the street welded...doesnt build anymore heat than a conventional differential would...i have never waited after driving it for any reason.

Never heard that, I'm sure it will be fine. The only problem with welding the spiders is you have no differential action, just like running a spool.

I ran mine welded for 2 years with no problems at all.

there should be no difference in diff temp running welded vs. a locker or anything

fordh8r · « **Reply #5 on:** Jul 19, 2007, 08:08:20 AM »

The only difference in temp there MIGHT be is cooler since now you wouldn't have the side gears working and adding to the motion of things in the gear oil creating more heat OR it could be the same with the added pressure on the ring and pinion with the tires constantly scrubbing in turns. Also, as far as hotter goes, I'd say the tires might be warmer from more scuffing especially if your last leg of the trip happens to be a windy (lotsa "S" turns) road. But both would be negligible differences I'm sure...

RUN IT and see...

It would be interesting to put a temp gauge on the diff to see how all this works out between the two set ups. Then you would have definite proof that can't be argued.

Dad is yanking your chain, I ran a Lincoln Locker for years in my 84 and will probably run one in my new rig once I find a donor 3rd member. My 84 was a dd and it never had an issue. About the only thing you can't do is run off-size tires when running a spooled axle.

Been running my truck for a few years welded f/R No problems. I put a V8 in the truck recently and still don't have any problems. Of course I don't run it on the street that much anymore but I did when it was a 22R and welded F/R Never had a problem. If you are two hours from Uwharrie where are you? I am about 3 hours from Uwhariie went there last year try the Daniel trail. I live in Salem, VA.

weld it up the only down fall is that your tires will wear a little faster, just make shure to clean all the oil off the best you can befor welding and let it cool often inbetween welds so you dont warp the carrier

90toy · « **Reply #14 on:** Jul 22, 2007, 08:40:24 PM »

anyone have any pics of a welded rear?

90toy · « **Reply #15 on:** Jul 23, 2007, 07:30:15 PM »

nobody has any pics or links on how to do it?

Rocksurfer · « **Reply #16 on:** Jul 23, 2007, 09:28:50 PM »

There are some very good threads around here somewhere.

SrOrangeCrawler · « **Reply #17 on:** Aug 09, 2007, 08:03:50 PM »

Just melt them spider gears together, Thats It! You should be making 8 welds, try to position the spiders so that you can weld every corner basically, its easy.

Rockdiver · « **Reply #18 on:** Aug 10, 2007, 04:41:26 PM »

this is best way in my opinion but you can just weld between spiders but put enough weld so it wont ramp the welds and break

Rocksurfer · « **Reply #19 on:** Aug 10, 2007, 05:53:06 PM »

That's the best way, there is no chance that they will break free when you weld a piece of plate in there too.

twistedtoy92 · « **Reply #20 on:** Aug 11, 2007, 09:18:16 AM »

yeah, just weld it!! i blew the spiders out of my 92 rear so i swapped it out, welded up the spiders nicely, and dropped it in my 84!! i drive it all over with no probs, just be more cautious in the rain and snow!!!! it wont want to turn as well!!

trailcrawler · « **Reply #21 on:** Oct 27, 2007, 02:11:14 PM »

if u weld the spider gears up i realize that the tires are gonna spin a little around corners but is it unsafe to drive on the road in rainy conditions?

chevyLUVtoyota · « **Reply #23 on:** Oct 27, 2007, 03:33:18 PM »

no.... best way to know....just weld it up..and you well figer it all out...dont be dumpin the cluch and it will not spin...

trailcrawler · « **Reply #24 on:** Oct 28, 2007, 07:25:00 PM »

i just welded my spiders up and i love it no regreats

Doof · « **Reply #25 on:** Oct 31, 2007, 10:20:25 PM »

ill try to find pics of my buddys 3rd he welded... he drove it HARD and i mean harder than hard. he broke the carrier clean off of the ring gear...it was nuts

i found em but i need to resize them or put them on the desktop....they wont load onto photobucket through my laptop

Hammerhead · « **Reply #26 on:** Nov 02, 2007, 09:43:27 AM »

I've been runnin' welded rear on 38.5s behind a V8 for years and this is my daily driver. Weld them suckers up and don't look back...

Stinky · « **Reply #27 on:** Nov 08, 2007, 12:42:54 PM »

well here she goes.....

1. pull the third out
2. pull the carrier out
3. pop the ring gear off
4. brake clean the piss out of the carrier(you want all the gear oil and
any oils OUT of the metal)....see if you can find someone with an old oven, n leave the pregnant dog in
there for an hour or so at like 400, that'll boil the oil out of the pores
5. then use a 1/8" E7018 stick rod(you wanna use this rod cuz it has a substantial amount of nickel
in it)...or if you can get nickel rods off someone or even buy em, run around 80-95 amps
you'll want a rod high in nickel, since the carrier is cast
6. then while its still hot(gotta weld cast while its pre-heated), just weld the spiders to the carrier,
and weld the spiders to the center pin... and since your re-heating the center pin(which is
already heat-treated, you will want to cut some piece of 1/4" plate to fit in the little windows
on the sides of the carrier to tie the sides of the carrier together(in case the carrier were to
crack, the plate will keep it together.
7. just make sure you keep everything hot while you weld on it, try and control the heat in the
carrier too, cuz if it gets too hot then it'l warp the ring gear mounting surface, then once your
done welding it, keep it some where it'll stay warm for a while and
that it takes a good 3-4 hours to cool down.... cuz if it cools off to fast, you'll have a

load
of subsurface cracks inside the cast, then when she gets torqued hard enough,boom!!
8. once its cooled off completely, you might have to do some clean-up so the ring gear will fit back
on....

not alot of people take their time when welding diffs, but if it's your only vehicle, that you drive
everyday, then do it right the first time.... then have fun destroying tires!!! haha, you'll get annoyed
after a while of it CONSTANTLY scrubbing, around EVERY corner.... and parking lots on warm days, haha,
prepare for a ton of people watching you park.... cuz your gonna be squeelin allllllll the time....

Some people may disagree with the ring gear removal, but its a whole hell of a lot easier to clean the spatter out of it when the ring gear is off.... and also spatter hitting the teeth on the ring gear will cause tiny stress fractures in the already heat-treated metal... might not sound like much, but after a while, it could cause a failure

ENJOY!!

also, i ran a welded 3rd for a while when i broke my lock-rite.... is nice b/c theres no random pre-loading ar engagement/disengagement.... its more predictable than an auto locker.... buuuuutt... its also way cheaper.... just make sure ya do it properly... as i wrote above...

Rocksurfer · « **Reply #29 on:** Nov 08, 2007, 12:48:19 PM »

Or you can ship it across the country to Mark's Differental Welding Service, best welded diff I've ever seen but shipping is costly.
