I was just wondering how difficult it is to change gears and what are the costs involved. It's for future reference in case I want to ever run 35's on my 62 that has stock 4.11 gears. Thanks guys.

Go to www.cruiseroutfitters.com / They are running a sale right now. Somebody else will have to give you a difficulty rating as I have yet to do it. I'm thinking about going to 35's myself.
 
Well, I cant tell you how many ring and pinions I have HAD changed. I say have had because I havent every done it and frankly it's to important (read critical) that it be done correctly to mess around with.

My brother just had his front and rear gears done on his F250. I know, different. His costs were 1600.00 US for everything.

Toys are a little easier because you can pull the third member and do it on a bench.

It doesnt sound to me like you need new gears if you are already running 4.11's and are only running 35's.

changing gears

Jeff,

From many posts on this BB, and others, consesus is NOT to change ring/pinion ratio's yourself, unless you are very experienced at it, have help from someone who is, or are training to be a full-time mechanic. Apparently, training and practice are required. That said, you can save a lot on the job if you are able and willing to pull the diffs yourself. This is a more doable project for the DIY mechanic.

To pull either diff, you'll need to pull the axles. The front is more complicated. Have you done a front axle rebuild? Wheel bearings/knuckle bearings/etc. If so, you'll be able to pull both diffs and take them to an expert to have new gear ratios installed.

Best Regards,
 
I've seen people pull their axles before. There is a local TLC club here with many folks who do there own work on their trucks. I'm sure they could help taking down the axles. As for the 4.11 and 35's, I've heard it can get a little sluggish around town. The 4.56 will get it close to stock ratios from what I've read. Thanks for the help guys.

Setting up some gears isn't THAT hard. Look in yout Toyota FSM and it has the entire procedure laid out for you. There are a bunch of rule of thumb tricks that people who set up lots of diffs use, but everything needed to do the job is in the book. If you're unfamiliar with measuring runout with a dial indicator, then it might be a stretch. If you have access to a worn or damgaed extra third member, don't be afraid to dig into it and take it apart. As long as you aren't keeping your daily driver off the road, give it a try. If you can't get the right gear meash pattern, or get the ring gear to have low runout,or feel you're in over your head, you can always take it to a pro to finish the job.
 
Installing the third member is the easy part, finding a pair to install is the hard part.
 
I think 4.88's put you closer to stock.
