Default 7.5 to 8.8 swap.

i have a 98 4wd 3.0 ranger with a 7.5 rear end.
an 8.8 from a ranger of the same year should bolt right in right?

Yup...what is it 93 and up will fit. I just did the swap in my 01 and everything bolted right in place.

The 8.8 is a stronger axle. It has bigger brakes also. Maybe has more gear choices than the 7.5. For everyday driving in a stock rig, it's not really any better imho.

The 28 spline 8.8 has the same size axle tubes as the 7.5; heck, they even use the same axle shafts. The only difference in the 7.5 and 8.8 28 spline is the center section of the axle.

The 31 spline 8.8 has larger diameter axle tubes and obviously 31 spline axle shafts.

The 8.8 is a stronger axle. The 8.8 has a larger ring gear. The 8.8 also has larger drum brakes.

There really is no need to swap them on a daily street driven truck.

Default Re: 7.5 to 8.8 swap.

I have a 99 Ranger with the 7.5 rear end. She is starting to howl and i get vibration and progressively gets worse at 55mph and above, tires and rims have been changed too. I suspect I could have a slight bent axle.

SO my logic is to fix or change the rear end or gears and axle. Since the 7.5 rear end is a pussy ive tried to find an 8.8 locally. They just dont exist in my area junk yards.

So back to option 1, changing ring and pinion and axle shaft. I want to also highten the gears. to say a 3.08 or a 2.73.

My question to you gents is.... what rear end has those gears from the factory i can plop out of a stock rear end and put into my 99 Ranger rear end?

keeping in mind cost is everything. I am rather poor lol. Local shop wants $500 just to change ring and pinion, thats not anything else.

I think if you are running a 2wd truck with a 4 banger they are a good upgrade. My dads truck was really bouncy in the ass end with the 7.5. We put in an exploder 8.8 and it "seems" like it holds the ground better. Like when you drive over tracks it doesnt kick all sideways now.

Default Re: 7.5 to 8.8 swap.

I found a ranger 8.8 out of a 99 ranger same year as mine but its a 4x4 for $100. I well assume I can use that rear end in my 4x2? Just make sure I get the spring plates when they take it apart. I forgot to mention, it too has 3.73 gears , same as mine.
