update on my quadvan 4x4 gen 2.0 setup---i have a second set of rims/tires mounted now--17X8 Ultra Toils with the 245/70R17 Nitto Grappler G2s. I had to grind down some of the lower pinch weld on the rear of the front wheel arch. When I get around to it, I'll do some grinding on the rear wheel well (no issues now, but if I ever need to put on link style tire chains I'll need extra rear clearance) although my plan is to run the smaller 16" BFG's in the winter anyway.
in all kinds of driving situations i always seemed to average 22 mpg out of a full tank, hand calculated. Now I've put on around 800 miles w/ the new, bigger tires (30.55 inch diam vs the 29.5 inch diam BFGs I had on for 2 yrs), I can report that actual mpg is still 22 mpg. The larger diameter means the engine is typically revving around 1900-1950 rpm at fastish hiway speeds (66-70 mph is my normal target), but the new tires are pretty **** heavy (46 lbs i think) and that offsets the slight gearing advantage. as expected, teh 3.55 diff ratio works perfectly w/ this size tire -- the transmission stays in 6th gear in most hiway situations.
since I have a 130" WB, the spare tire now is far to large for the opening (i.e. rear diff housing is in the way) so I had to run that red strap thru to pull the wheel back as I tightened the spare wheel mount cable. works fine and hasn't moved around, but long-term plan is to fabricate a rear door mount. I'm not thrilled w/ the current options commercially available but let's see what evolves.
Note: i've added a pic showing how John at Quadvan hacked off 2.5 inches from the rear shock hangers and rewelded and painted them. This was a modification I've wanted to do for a while -- REALLY helps off road clearance back there. With the 2" rear lift, John said there's actually around 4 inches of extra travel in the stock shocks so I could have asked him to hack off more than 2.5", but as you can see from the pic there's not much point to go higher.
I'm on the build list for an Aluminess front bumper in the next run (June). I'm leaning toward clear coated aluminum rather than black powdercoat.
I have used the 4WD a lot in the past few months. Snow, mud, sand. Recently was on a USFS road that had running water and muddy ruts everywhere....the kind of back road that is fine in, say, a stock 4WD Tacoma but can be a problem for some SUVs that are FWD-based AWD. The van had no problem at all. Huge thumbs up.
I have the Gen 1 quadvan 4x4 and my front driveshaft caved on me after 1year. The cv boot on one end of the shaft lost the grease boot, shed grease and failed Quickly while driving on the highway. By failure I mean loud humming drivetrain noise coming from the front end and got worse and worse really fast. Pulled over, got a tow to a ford dealer who didn’t want to do anything so I told them to pull the shaft so I take the van away. Quadvan shipped me a new shaft really fast and it is re-installed and everything is good again. If I have a front shaft problem again I’m going to have to go gen 2. I got lots of use in 4x4 this past winter. With my Toyo 10 ply winter tires this van is a tank in the snow! Just put on my BFG all terrains today and fox rear shocks. Might tackle winch install this weekend.
Love this van .
