I am looking into welding the gears in the rear. Anyway what kind of problems could i run into having welded gears? I know that the tire will wear differently and a slight churp every now and then on the road but not like a lock right so what kind of stress facters could i run into? Anything else?

don't be shocked if you go thru axle bearings a tad bit more...

Expect the tires to churp around every curve. There is no "now and then too it." One tire will slide/skid around every turn weither you hear it or not. Not that that is a bad thing. Just kills tires fast if it is your daily driver.

You'll hardly notice it. If you don't mind the slightly shortened tire life. I've never had a Detriot but I know it's alot better than a Lockright as far as driveability. No banging or clanking or driveline backlash, just a little scrub. Mine would only chirp the tires if they were aired down. I just wouldn't be hauling real heavy payloads around. Something has to give in the corners and with alot of weight it might not be the tires.

The welded diff is great off road but it sucks in slow turn situations like parking. Not only that, every time you park, expect your truck to sit sideways unless you back up and then go forward. This especially is bad if you have soft springs. I just got rid of my welded diff for an ARB and couldn't be happier. The welded diff did it's job well but if it is your daily driver I wouldn't be looking into it for the long term.

I have both a welded and an open thirdmember, the weldd rear end is enough of a pain around town that I swap it for the open after every 4x4 trip (wich for me is actually only about once a month... <IMG SRC="smilies/tongue.gif" border="0">) but it kicks enough ass off road that I swap the open for the welded before I go out for a day or more.

my last trip took me on some VERY windy mountain roads, keeping it around 25mph the tires squealed through every turn like I was doing 125, oh, and having a stock runner with 30" tires I get weird looks whenever I pull in to get gas or air up.

one tech note, I would reccomend welding with something with some give and compatible with high carbon steel like nickel rod, and not 7018 wich is stronger but still mild steel and not ductile enough to be in a rear end

Dang. That seems like alot of work for what you money you save instead of buying an ARB.

I tried to weld my spider gears with 7018, which was reccommended. But I couldnt get it to strike worth a darn. So I cranked up the juice on the wire feed (lincoln 155) and it worked great. had it for 8 months or so now and love it. Even on the street. Sure, the turning ability decreases, but it sucked anyway...

Hey Toy Penny did you have the rear welded. Hows does that affect the steering. I can really see it affectding the turning radius if the rear was welded. If you welded the front do you not have manual hubs?

you still have manual hubs but you can expect to driveing off road with one of them unlocked if you plan on turning. go with the welded (spool) in the back if you are going to go that route

I have always been happy with the welded rear in my '88. Never squeals, only scrubs a little. I think the long wheelabse helps.

It's a lot of fun to do donuts with <IMG SRC="smilies/biggrin.gif" border="0">

the rear of my 87 toy has been welded for over 10 years and was a daily driver until just recently I absoulty love it! I have not had a single problem with it except it does wear the tires a little faster. it does chirp the tires but if you keep 32lbs or so in them its not so bad and besides I love the strange looks I get in parking lots!!! <IMG SRC="smilies/bounce.gif" border="0"> <IMG SRC="smilies/bounce.gif" border="0"> <IMG SRC="smilies/bounce.gif" border="0"> <IMG SRC="smilies/bounce.gif" border="0">

I just installed my new set-up. When the SAS took place, I took the rear diff wid the lockrite and put it in the front, I took the new set of gears and 'bender welded'em and I put it in the rear. Am looking forward to many years of enjoyable wheelin'.... <IMG SRC="smilies/biggrin.gif" border="0">

Welding diff with gears installed?

Can you weld a diff with the ring gear installed? Can you weld it with the carrier in the housing? Will short welds heat the bearings too much? What about with the whole thing just out of the axlehousing?

I opened my big mouth, and I'm helping someone who I've never met to weld his rear, I don't know how capable he is with pulling the 3rd, and I don't want to spend all day pulling it, cleaning it, tear out the carrier, re-setup the diff, etc, so I want to just drop it, weld it, put out the multiple gear oil fires, and remount it, will I really fawk up his diff?

You should be able to weld it with the ring gear installed... A buddy wetted down 3 small rags really thouroughly, and it kept spatter off both the ring and pinon gears pretty well from what he said.

That was just pulling a 3rd member and welding. No parts removal.

He also cut two pieces of 1/4" plate to the shape of the gap between the spiders and burned one down on either side of the spider gears. Just exercise judgement: The more wire you pour into the diff, the stronger the welds are... but the more heat you pour into it... the weaker the carrier becomes.

Gear oil is EXTREMELY hard to burn, BTW. It probably won't catch.

Excellent, that's what I wanted to hear.

I've lit puddles of gear oil on fire by having them in the path of sparks from a grinder...I never thought that it would light up, until I had several small fires on my front porch! :eek:
