    D50 wheel bearings spinning on spindle

    Might also want to make sure the preload is correct and not too tight.

    Where to buy 16.5 tires

    I don't think they will. I'm running 33's on a D44 truck stock and I don't have any clearance issue, but there's not much left for anything larger. Might be able to do 35 but I doubt 37's. Also would need to have the right backspacing - one set of 33x12.50r16.5 rims I had would rub when making...

    Where to buy 16.5 tires

    Yes, difference is the bead angle, but I disagree about 16.5 failing..... done quite a bit of off roading in some nasty terrain with my rig on 16.5's and never had any issues. If you're going to air them way down then it might be an issue, but any tubeless tire is prone to have issues at low...

    Power is Power, Right?

    Yes and no. Horse power is the same, but the actual engine power curve and engine reliability is not. HP is a function of rpm & torque - 400 hp at 6000 rpm and 400 hp at 900 rpm are the same power, but vasty different torque. drivability is going to depend greatly on the shape of the power...

    Where to buy 16.5 tires

    What size? I had no trouble getting 33x12.50r16.5 BFG AT tires for mine ~2 years ago. Had them in stock at one of the local tire chains. (forget which one) 35-12.50 seems pretty common to find too, though not going to fit those without a lift. Not sure about smaller sizes, though I'd bet a...

    Two questions....

    Partially that's perspective - it's about 1/4" thick IIRC

    Finding more gears

    ZF5 and a US Gear/ DNE2 box will give you 9, will work like a 2 speed rear end.

    Two questions....

    That's the newer style - much better than the aluminum bridge both because it's not going to crack like mine and less wear. Yep, fun trip. Just got done with the engine too.... had reasonable warning something was going wrong but the point where I realized it was something more serious (had...

    Two questions....

    Well, on the other hand the truck made it ~100 miles on the freeway at about 15k gross (admittedly flat) with a 1/2" hole through one of the pistons before loosing the wrist pin..... :eek: Was still running after that too, though it lost oil pressure from dumping the cooling system into the oil...

    Two questions....

    Per official Ford spec book, the torque is 20 ft/lb (27 n-m) Also, be careful to tighten them evenly, especially if you have the older style aluminum bridge rockers. I lost a freshly rebuilt engine from uneven tightening of the rockers.... :eek: (rocker pivot cracked at one bolt, cracked off...

    Used ZF-5 speed, Question on checking condition

    Yah, but more work than it's worth IMHO when a regular twist drill will work fine on the aluminum and the holes are reasonably sized. Would also probably want to check if the mag drill bits were ok for use in aluminum since it cuts differently. The difference between ZF & T-19 isn't the...

    Used ZF-5 speed, Question on checking condition

    ZF5 case is aluminum.... don't think a mag drill will work too well. LOL Should be fine doing it with a twist drill. I'd do the t-case pump mod while you're in there to save any issues down the road - simple to do while it's apart.

    Brake Pads

    Wouldn't use ceramics - likely to eat rotors since they're so hard. Harder pads will last longer themselves, but will also wear the rotor more. Personally, I'd rather do pads more often and save the rotors. Wish I knew what my pads were - They're probably somewhere close to 100k miles and...

    Used ZF-5 speed, Question on checking condition

    Not really any way I know of the check the ZF. I'd pull the back half of the t-case off since it's just a bunch of bolts holding it together and that will let you check the chain and pump. ZF input shaft length is different so it doesn't engage the pilot bearing correctly which leaves the...

    pistion suggestions and questions...

    I went 0.015" on mine. Would probably have gone 0.020" if I did it again, since the coating adds about 0.005" I don't think heat reaching the rings is going to be much of an issue since the ceramic coating will reduce the heat flow into the piston. The issue is that by removing materials...

    HP and torque numbers for comparison

    158 hp sounds like the high altitude version, I think the most common setting is 165 hp. 7.3 was 175 hp IIRC, maybe 180 for later ones. Don't think I've seen an official spec for torque, but the Banks turbo literature gives ~300 for the 6.9 & 320 for the 7.3. Pretty much every car/truck...

    US Gear Surprise

    The US Gear internal wire model and DNE shift motors will interchange, and the US Gear box can be fitted with the internal type control switch. I would be surprised if the external wire motor on the newer US Gear units couldn't be swapped for the older motor - as long as the casting and the...

    Scrapping engine, any valuable parts?

    I'd save the crank, rods & heads unless you just can't afford the space. One of those things where every one that goes away is gone forever, and every now and again you need them. Little stuff too - pushrods, lifter keepers, oil jets, intake, valve covers.

    Benefits Of A Electronic Fuel Pump?

    Well, yes, of course a quality pump is better than a cheap piece of junk one.... Quality mechanical vs quality electric might be different. OEM use of electric vs mechanical pump has zero to do with reliability.... Looks at how many industrial/equipment type engines use.... mechanical fuel...

    Transfercaes

    Probably a 1345. Both look about the same and are functionally almost the same except ~90% of the 1356 cases have the slip yoke. The in cab shifter is slightly different, the the actual case shift setup is that same and AFASIK will swap in. Seriously, run down to the junkyard.... good chance...

    Finally got lift pump changed. Runs, now ABS light on and dead speedometer?

    Tangent, but note that the VSS on the rear axle was standard for 87+ (IIRC), so having one does not mean you have an electric speedo, though it's the same sensor with or without. Earlier years used it solely for the ABS, and had a mechanical speedo with another sensor to feel the cruise & E4OD...

    Electric. Looks like 91 is the last year with a mechanical speedo.

    Transfercaes

    Ford 80-94(97???) cases are all the same 6 bolt 31 spline input. There is some variation in the output with the later 1356 cases, most had a slip yoke but a few had a fixed u-joint flange on the rear output. An 87 is likely a 1356 case with a slip yoke. Probably the c6 cases above are...

    Finally got lift pump changed. Runs, now ABS light on and dead speedometer?

    I'd guess you jiggled a connection somewhere. The speedo gets signal from the sensor on the top of the rear axle, and splits this out to the ABS system and I think the trans, so a lack of speed sensor signal into the speedo I'd expect to cause the issues you're seeing. I would check the...
