I have a 1992 Ford Ranger with the original 7.5" rear differential and gear ratio.I hate this thing because it's simply too high geared in the rear.So,I bidded on a Ford Traction-Loc for it on eBay last night.It's used,but I did my research and everything is there that I need.It also has a 4.10 Ratio.

So,now here's my question. How Do You Go About Installing One Of These Things!?!

Like I said,it's the original rear end and I doubt that it has ever had a fluid change.So,I'm going to make a trip up town to get the correct amount of oil that I need to go in the rear end and also a new gasket for the rear cover.Now,after I take those bolts out of that back cover,I'm lost.I'll be able to see everything,but I won't know what to do with it.I figure that I'll have to disconnect the driveshaft and take the nut out of the yoke on the rear end.Then what?

If anyone knows exactly what I need to do or not to do,or has any advice or comments on what I'm doing,please let me know.I figure that this is something that can be done at home and I don't want to have to spend more money than I have to to get the job done.

Any insight is appreciated.

First, I think youre 1992 Ranger may have a 8.8 rear instead of the 7.5 you mentioned. You can check this out for sure by the data plate on your truck. Also, check out www.therangerstation.com for some good information.
Second, they didnt use gaskets for the rear cover,just silicone.
This is a big job requiring special tools to set the gear pattern.
I would take it to a garage.
You didnt mention if your truck was a 4X4 or not . If it is, you'll need the same gear ratio for the front as the back.
Hope this helps

Thanks for the tip.It's a 2WD.I'll probably end up letting my cousin do the job.He has everything that one needs to do such a thing.I'm sure that my rear is a 7.5".I ran the numbers on the tag when I bought it in August and everything checked out.The only Ranger's that they put the 8.8" rears on 1989+ was the 4.0L V6 models.Mine has the 2.3L 4-Banger .Still,a 4.10 Gear Ratio would be ALOT better than the original 3.07 ratio .
