Well, the time has come. Rear diff is going out on the 4Runner. 97 model with 230k miles, auto, 3.4, 285/75s. I always said I’d regear it if I had to do a diff. Now I’m not so sure. We pull the SoCal camper from Western Ky to near Asheville NC a couple times a year. Although lately we have used the 04 v8 runner. The 97 only get 4K to 6k miles per year, if even that now. We mainly camp and trail ride with it closer to home, well within a couple hours. Question is , is it really worth it to spend the extra money for the front diff and reheat to 4.88 or just keep the stock 4.10 and fix the rear On a truck that mainly sits in the driveway? Or am I going to be sick that I didn’t go ahead and do it? Obviously the 04 pulls the teardrop better anyway, but I love my 3rd gen. Wife wants to do lift and tires on the 4th, but I’m not sure how she would like that as a dailly driver as it’s not going to ride as well as stock. Decisions, decisions

Does your 'wheeling demand lower gearing, or is regearing for bragging rights? I assume your 285s mean that the transmission isn't in overdrive as much as you'd like it to be, right?

Mainly for pulling the teardrop. OD is good for the most part. I don’t do any serious wheeling. Just trail riding and mud occasionally. Gearing ain’t going to make any difference for me there. Only place it really matters is on the highway with the trailer. If I’m pulling with the cruise on and it shifts out of OD it may not ever go back unless down hill. If I’m controlling it I can make it go back to OD. And she’s pretty sluggish off the line all the time. I can’t make myself believe I’m going to benefit that much from it. Especially no more than it’s driven. And the extra money for the front I could save or put toward something like new shocks or lift for the 4th gen. They getting pretty weak. And, if we’re going more than a few hours from home we been pulling with the 4th gen anyway and just using the 3rd gen closer to home.

4.88s due back from East Coast Gear Supply tomorrow. Hope to have them installed by the end of next weekend.

Gears in. About 500 rpm higher at 70mph. Much smoother acceleration. So much quieter than the howling rear pinion that was in it.

two 70 mile highway runs today to and from work. Had the rear brakes adjusted too tight and fixed that at lunch. Main thing I noticed was with the cruise on at 76mph, 2800 rpm it didn’t have to downshift going up any grades. Granted it’s pretty flat here in western ky it would have to before. Mileage was not better on this tank, but I was varying speed on both trips, and, again i had the brakes too tight this morning. Looking forward to see how it is with the teardrop later this month.
