572

[M4wdFab]

took the porto ban to the hub and sacrificed to get to try and save the spindle.


success!  cut and ground about 1/2" of the spindle off and was able to remove spindle nut.   


hub replaced, rotor on right side, calipers and pads on both rear sides changed.  made a two bolt retainer clip to hold 14 bolt key way in on the trimmed down side.  all good. 

new brake line run, ready for bleed tomorrow and standard race prep for Saturday. 

[M4wdFab]

race prepped and ready for Saturday minus fuel top off and bolt on rear fire extinguisher borrowed to bro

[M4wdFab]

washed and flat changed
shredded BFG beads broken, wheel looks OK

needs leaky steering filter fixed for the weekend. 

[M4wdFab]

2 good wheels and a 3rd rock ring freed from shreded BFG pile
steering leak fixed, found suction line pressure gage on steering not up to the task of ridding along.  removed and plugged.
window net removed and seat cleaned.

pulled hood and started looking at wilwood brake install, should be doable.  job for another day.    current brake booster might not have another race left in it before master rips off it. 

[M4wdFab]

one trep mounted up, 3 KRTs dismounted.

cracked a KMC trying to straighten, boo.  might give it to one of you aluminum welder guys to fix.

[M4wdFab]

fueled

gona try to end up wheeling somewhere this weekend. 

[M4wdFab]

no issues this weekend.

treps performed about what i expected   they still have air in them which was the goal of the weekend. 

[M4wdFab]

RCVs getting really loud.
tore front end down for inspection last night.
4 or 5 pinnion chips so its going to get a new gear set tonight. 

spindle bearings hosed of course. 
RCV grease good and clean. 
King pins tightened up

that's a low pinion Chevy axle being run upside down, right? which leaves it driving on the coast side of the gears when going forward, or would it be drive side since it's always "in reverse"? I guess drive side?

just sanity checking myself and thinking about gears...

[M4wdFab]

same as yours but running backwards all the time on coast. 


this setup was 0 to -1 back lash and a welded nut before KOH.  one of the longest lasting thus far. 

i started to price out a new front end build.  going to do a 40 spline 14 bolt.  its going to be spendy.  boo. 

[M4wdFab]

fresh drivetrain parts for trailer stock ordered.

front and rear gear sets
front and rear spare yokes
splindle hub bearings / seals

Have you considered to put in Dana 70 gears in it? Jana76

I'm going out on a limb.. But I would assume your thinking 14 bolt due to the 3rd pinion bearing to reduce any deflection that might be going on in your gear set?

[M4wdFab]

i have flogged the shit out of my rear gear set is more what im going on and its fine (runs backwards too)

The rear gear set in 572 was in 571 racing for 3 years, and now has been in 572 since new.  its broken 2 stock 14 bolt shafts, and 1 yukon chromo shaft, 3 rear drive shafts, and a transmission.    the thing has been zero maintance since new and still looks new lol 


I have looked into the Jana70 long ago.  dana70 parts are very expensive, custom bearings also.  it makes gear changes 5-600$ and spool costs are were crazy when i looked into it.


i plan to do a full 40 spline conversion and 14 bolt center chunk, salvaging my solid knuckles and 3/4 ton brake kit, PSC ram / steering tire rods / Artec arms.  The build will require new housing / truss, gear set, 40 spline spool, 40 spline Branik 300M shafts, CTMs, new Solid C's/kingpins, 40 spline hubs, 40 spline spindles and bearings, 40 spline drive flanges, 14bolt inner axle seals, 14bolt 1350 yoke. 

its gona hurt but i dont see any other solution to my gear set issues and RCV issues.
