Here's where experience and age does make a difference. Everything being said about welding up your gears by others is 100% true. It is also dangerous on the street. Do people do it? Yep, they do but it's not advice I'd give to someone looking for a street posi or locker. It also breaks parts like axles. Your situation might have been different. Maybe it was a lighter car with smaller tires. I don't suggest it in a truck. Cops give tickets too for barking tires thinking it's a burnout, so they cite you for exhibition of speed. If you want to make your suggestion to where it doesn't matter if you're right or wrong, You can say, what worked for me when I was broke and didn't have alot of cash I did..... And the others can chime in and be against the suggestion as I would have been against it too. Welding spiders is for dirt trackers or off roaders. It's a cheap locker or spool but it's not good for the street for several reasons. You get that **** on some snow or ice, you could end up dead over it.
Just sayin', be willing to learn and be willing to be stand corrected without a chip on your shoulder. I'm not going to toot my horn here, but I'll say I know a ton of **** about these trucks, and it wasn't that long ago, I was corrected. Funny part was, about 20 others were right along with me, and this 1 guy pops up says and NO that's wrong. So I checked it out, and that 1 guy was right.
