General Updates
Heat
Well I decided to finally replace the heater core as I was having a tough time keeping the windshield defrosted and it was getting too cold to just have a window open. It's about the job you would expect except when you go to actually remove the heater core and it is massively ballooned likely due to letting straight water freeze in the core.
Since I had to pull my steering column to do this repair I did take the opportunity to swap in a tilt column that I picked up at the local Upullit yard. It makes a world of difference to have even that small amount of tilt (bigger guy in a little truck)! I'm also working on mounting my cruise control stalk ala jimbote. Will post pics when I get to that.
Since I only had HIGH fan speed I also needed to address my fan resistor pack which is notorious for corrosion in the electrical connector damaging the pack or the connector itself. Well mine was so corroded I could not separate the two and had to basically cut the two apart. Even then the spade terminals would not come out of the female counterparts so I had to buy myself a repair kit from Ford and solder it in. It is very nice to have heat and I have to say it is quite a bit better than my Jetta's heat.
Aero mods
I tried my first aero mod: I borrowed a hard tonneau cover from a buddy at work. Surprisingly it really hasn't improved my mileage. I put one tank on it driving exactly the same commute (before the weather cooled off) and got the same mileage. I don't have a picture but it's hideous.
Gearing
My biggest update is I have now swapped in a rear axle for one with taller gears. As mentioned previously my truck came with a 3.73:1 rearend which was tons of fun with plenty of snort but I was spinning a little faster on the highway than I liked. Actually I was spinning faster (2450rpm) than I was calculating (2350rpm) for my commute speed of 65mph. By my calculations a 3.08:1 rearend should drop my cruising rpm by 409 to around 2000rpm. Perfect right? Well my new rearend has me running right at 1900rpm @ 65mph. I'm more than pleased with how quiet the drive is now (will take a measurement at both rpms to compare) but am a little concerned my 2056 turbo will not be very responsive in 5th gear at all....that is unless I'm breaking the law
. Anyway, what is nice about this steep drop is my 4th gear cruising rpm is exactly where the 5th gear was before so I now have a true overdrive for bombing down the interstate.
While I was swapping over axles I decided to fix the parking brakes which have been inoperable for quite some time. I threw everything back together but since have been struggling with dragging rear brakes. I've had the drums off at least a dozen times per side and
think I may have finally tracked down the issue: my OReilly brake cables (before you harp on me, I was assured by a trusted parts guy they had had luck with the exact parts on his Ranger) are 1) not releasing the parking pawl 2) pushing the rear shoe into the drum. I've just disconnected the cables and adjusted the shoes and will give it another commute to see if the dragging is solved.
