How would you go about switching to 4.10's from 3.73? Some of the trucks I am looking at have the 3.73 and I want the 4.10 since I plan on getting 33's. Is it a big job/cost/pain?

 

I was quoted $1,000 + dollars to do mine.

I just bought a FX4 level II axle from a junk yard and paid around 500.00 after everything was bought fluid and hardware

 

I bought an 8.8 and it cost me $120. But I think the average cost is about $500 for gears and install.

 

Its cheaper just to find a Ranger axle at a junkyard that already has 4.10s. Then bolt it right in

 

i bought a 4x4 axle for 400 at the junk yard. and thats all it cost me cuz i put mine in myself.

 

yeah thats what i did

 

If your 2wd just get a axle. If your 4x4 look for $400-$1000 depending on shop for a gear change front and rear. Yes its a big job, it can take a long time, its a pain if you dont know what your doing.

 

i have a 2wd and i switched from 3.73 to 4.10 in like 3 hours but i also had 3 other guys helpin out to. it wasnt to bad

 

I'll be nice and won't say anything to a 3 hour axle job with 3 people in 3 hours.

 

yeah it wasnt bad at all. umm the only reason why it got done in like 3 hours was because i was at school and i decided to do this as a project and it had to be out of the shop before a certain time. so we had to bust our butts to get it done

 

I did my axle swap, new rear lift shocks, rear lift, and was out the door in like 20-25 minutes.

 

Awesome dude, I have been looking for a while now for my 4.10. I actually went to the junkyard yesterday looking for one. I have been there so many time that I have lost track. I probably saw a dozen 3.73 7.5 axles and one 8.8 3.27.

 

Do you have to change front and rear axle? and what is 8.8?

 

8.8 is just another axle that the some of the Rangers came with.

 

yes if you have a 4wd, and want to use the 4wd you MUST change BOTH axles to matching gear ratios or only be off by a tiny amount like 5.14 and 5.13...

 

I put mine in myself. The fluid is what was the shocker 12.99 for a bottle of fluid.

My buddy and my dad helped. My dad watched mostly as me and my buddy put it in. about 2hrs I think

 

its like $4-5 at wally world, unless you demand to use the Mobile 1 or Lucas.. then it gets expensive

 

for the 31 spline Torsen, you must use synthetic fluid, i think thats what he was talking about.

i did both of my axles myself, for $140.

i went from 3.73 to a 8.8 31 spline torsen 4.10 and a front with an aussie locker and 4.10

 

so once i get my 32's all i need to do is swap a 4x4 rear axle to have 4.10's and i'm done?? (mine is 4x2)

 

The axle I got was the 31 spline torsen so I had to use the synthetic


U dont have to go to a 4wd axle they have 2wd axles with 4.10's in them

 

how can i tell which axle has 4.10? mine does by any chance? lol that would be beautiful

2001 Edge plus 4.0 2WD stepside

 

You can look on the sticker on your door panel and it will give you a code, just look that up here and you'll find out what you have.
Match the number up on this chart




Or

Little tag on the diff. cover it will say like

ok cool thx !!!

 

Yup you got 3.55 gears same as what I use to have.

Just find a explorer axle with 4.10 then you can have rear disk brakes
they are easy to find

Finding a ranger axle with 4.10 may be more trouble than it is worth unless your lucky like I was. I had 2 different ones to choose from.
