5 Lug to 8 Lug 44 TTB Conversion

There are a number of ways to convert your front end to an 8 lug pattern:

  1. Solid axle conversion - This is generally a huge and/or an expensive undertaking.  It is also generally the strongest and heaviest option.

  2. Conversion to a Dana 44 HD or Dana 50 TTB setup form a F-250.  This requires conversion to leaf springs or creativity and customization to allow for radius arms and coils.  This can be expensive and requires sometimes difficult to locate parts depending on where you live in the world.  And for the cost and effort you basically just get 3 more lugs on each side.

  3. Some have considered a custom wheel adapter from 5 to 8 lugs.  I made an attempt and designing one a long ways back before my solid axle conversion and gave up.  It just didn't seem safe.  I contacted the big wheel adapter fabricator of the day and they said it was impossible.  That said, it can and has been done.  You simply make 2 adapters.  One that fits the hub pattern and anther that fits your wheel pattern.  You then map out holes between these two different lug patterns that will allow for mounting these two different adapters together.  For a 5 to 8 lug pattern, your adapter to adapter holes will not be evenly spaced, unless you make a very wide adapter.

    A 5 x 139.7 (5.5") 1/2-RH to 8 lug 6.50" X 2.00" Wheel Adapter looks something like:


    This can save a bundle of money and headache, but still doesn't look right for heavy abuse applications.  Having one of these may also allow you to run different lug pattern wheels front and rear, yet still only need to carry a single wheel.

  4. You can take a 3/4 Dana 44 spindle, hubs and brakes and mount it on your 44 steering arm after you remove your caliper wings.  This would be the best compromise allowing for a stock strength setup with minimal effort not requiring any special or custom parts and without adding a ton of weight to your front end. 

    First off, an F-250 has a different sized steering arm than used on a 1/2 Ford.  Making a Ford 3/4 steering arm work, you would have to get creative on the steering arm with a welder - a place most would not want to mess with.  To make this conversion work, you will need to find a straight axle 3/4 ton Chevy 4x4 donor axle/truck (NOT a late 1980's with the IFS).  You will need to make sure that the donor axle you use has the caliper bracket in front of the spindle and not inbetween the spindle and knuckle.  Once you have your parts, strip your Ford steering arm of everything, including the spindle studs.  Cut the break caliper brackets off.  Now install everything from the spindle studs out with your Chevy parts.  8lugswap

    Wish I knew this trick back in the day.



8 to 5 lug Conversions

Every once in a while, someone wants to fit 5 lug wheels on an 8 lug axle.  There are a number of ways to do this:

  1. Generally the most economical way to deal with this is to go purchase a pair of 8 lug wheels.  These should fit without issue and you can get just about anything in 8 lug now a days, to include 15 inch wheels with beadlocks.

  2. There are adapters that allow you to go from 8 to 5 lugs.  These are actually two adapters in one.  One mounts to the 8 lug hub and the other mounts to the wheel.  Offset holes are configured to allow the adapters to mount together.

  3. Hubs can be modified to allow for different bolt patterns.  You may need to fill in a hole or two as the bolt patterns will overlap at least at one point.


  4. Depending on what axle you have, you may be able to use 1/2 ton hubs that may fit perfectly and allow you to mount unmodified wheels

  5. Most axles, front or rear, can be outfitted with custom hubs that can have just about any bolt configuration.

It is important to note that if you change your bolt pattern, your wheel may still not fit over the center hub and require that you enlarge their center hole if you plan to run them.  This can be done on a lathe or with a hand grinder with mixed results.

Be aware that these u-joints are designed to use "full-circle" snap rings and so will require a little machining of the ears of the yokes of stock shafts to allow the snap-rings to fit, or the use of custom D60 front shafts designed for full circle snap rings.
These u-joints are also much stronger than stock Spicer shaft yokes and are rebuildable.

Rumor has it that you can preload your bushing by adding as much as 1/8".  More may cause coil bind which is very hard on parts. An additional spring cup on the top of the spring adds about .060".

Dana 60 top Kingpin Removal

 

To remove the top kingpin use a 7/8" hex rod bent into a giant Allen key, or

cut down a chisel with a 7/8" hex backing, drop it in the kingpin so that enough is exposed for a heavy duty socket - and use a 3/4" drive socket on a t-bar with a cheater bar

 

Thing that don't work:

Several 7/8" nuts welded to a grade 8 bolt welded to a long bar - bolt and welds shear

Long chrome plated 7/8" (outer) lug nuts - outer corners get rounded off

1/2 drive ratchet, cheater bar and lug nut - 1/2 ratchet breaks

7/8" wrench, cheater bar and lug nut - wrench bends and/or rounds lug nut
