Alright, So its been awhile. Well lets start it off with something good.....I gots me somes newz rubberz!
I was sort of forced into getting some new tires (spike strips will do that). So I picked up some 35/12.50/17 Cooper STT in load range E. I love these tires, I have run them before on several vehicles and have nothing bad to say about them. I think the 35"s fill out the stock wheel well nice. I have just a slight rub at full lock on the sway bar, but nothing that will cause any issues.
As for the Spyntec Kit some have asked about it. To boil it down you are replacing you unit bearing with Dana 70 HD outers with 35 spline stub shafts. Now that I have a few thousand miles on it, here are my thoughts.
-Increased fuel mileage (I am settled into an average of 14.5mpg mixed 17mpg highway with conservative driving)
-Less wear on front end and transfer case as I am not turning the axles, ring/pinion, front drive shaft all the time
-Ability to have 2Low (locked), great for backing heavy trailers up hill
-Stronger front end with outer being supported by two larger set bearings spaced farther apart
-Ability to run 3wheel drive if an axle fails / disconnect axle if failed
-Less costly repair if a bearing does fail (approx $40 for a set vs. $280 for a unit bearing)
-Lifespan unlimited if bearings maintained properly
-Cost, its not cheap ($1750 to your door) plus labor if you cant do it
-Maintenance, bearings must be cleaned/repacked every 20k miles (annually)
-More moving parts (in this case all stronger...sort of nulls out)
-Hubs stick out approx. 7/8" beyond wheel
-Need to modify hubcaps if you intend to reuse
-Length of time for cost recoupment ( in my case mileage indicates 22 months to break even)
