Re gear help

hello guys I have a few questions. So I work at a small mechanic shop during the week for experience while I'm going to school. I was wondering how do I re gear my truck? I asked my mechanic and he said he did one a year ago and will help me. He lets me use his tools and will help me if I need it, but I just need help in how I do this correctly and buy the correct parts.

I want to get 4.10 ratio in the rear differential. I currently have the stock gears on the 5 lug automatic. Has anyone ever done a re gear and how do I order the correct part for a 5 lug automatic?

Not trying to go cheap on parts the labor is free, also if you know how to add a locker that would be sweet. please someone share there knowledge.

 

you have to order a ring and pinon for 4:10 gears for your particular axle, and a shim kit that goes with that.. Also look into the "trutrac" made by eaton. It goes posi when slippery and disengages when in turns.

 

Visuals, while not technical, will help...

I've been working on my Toyotas for around 20 years, and would NEVER attempt
to do a ring and pinion on my own. Technically, doing brakes is a walk-in-the-park
compared to any gear-box work. I figure I save enough by doing just about everything else
on my own that I can afford to pay a pro to do this.

Also, this is one of the few jobs where the parts cost much more than the labor.

Since you know someone who has done it, and has the tools, make sure he is with
you the whole time if he is willing. He can also answer the questions you have asked this forum.

Just my 2 cents worth.
