This morning I put up a post about the FJ Cruiser T case going into the 2nd gen Tacoma. It has gotten a lot of attention but particularly from the 4th gen 4Runner owners. I've had a number of emails me asking questions about it and what makes it harder than doing the swap into a Tacoma. So I'm going to tell you.
First off lets discuss the 4th gen 4Runner's T case. This T case has a locking center differential in the V8 model's and is full time 4wd. The V6 models have a Mult-Mode T case that has 2wd, all wheel drive, 4wd and 4lo with a center differential.
Both of these t case's are fully electronic and because they are they are very prone to failure. Dirt and water can get into the rear actuators easily and when it does it plays havoc with your system. On the V8 T case's they tend to leak from behind the actuator. It can be fixed but usually does not last long.
Once these transfer case's start to have problems it begins to multiply very quickly. Soon it's time to decide whether to get a new case, used case or swap it out for something entirely different. That is where we come in.
RockSolidToys has been the pioneer in T case conversions for the Toyota 120 platform vehicles and will continue to work on bringing you options that the factory should have provided.
We were the first to put an FJ Cruiser T case into the 4th gen 4Runners and to turn a 2wd 4th gen 4Runner into a 4WD 4Runner using all Toyota parts.
This post will show you what it takes to put the FJ Cruiser T case into the V8 4Runner and make it work.
First off you'll need the transfer case from an FJ Cruiser that has the automatic transmission or from the 5th gen 4Runner with the manual shifting transfer case which is the same as the FJ T case.
In the picture below is an FJ Cruiser T case that we have modified to a twin stick T case. We'll get into that in a bit.
