    Five years and finally on the road!

    As previously mentioned on Mudd back in 2016, I purchased my 2/71 FJ40 from pretty much the original owner (he owned it since '73) after seeing it sitting on flat tires beneath a pepper tree. The owner was raking his front yard when I approached him and asked if he ever considered selling his...

    Heater Box Foam Question

    Performing a refresh on my original 1971 FJ40 heater box. I have read most of the heater threads on mud and they say to use 1/4 charcoal foam. One thread referenced using open cell, another closed cell, and a third mentioned neoprene. Any thoughts on the "type" of 1/4 charcoal foam?

    How does it get this bad?

    Finally back to wrenching on the 40 (life got in the way for awhile...) Anyhow, I removed the radiator and had it thoroughly cleaned at a shop. I figured I would replace the thermostat while I was at it. When I removed the hose, this is what it looked like (see photos). What causes it to get...

    Finished rebuilding three out of my four rear wheel cylinders on my 2/71 FJ40. Of course, the fourth and final wheel cylinder piston and adjuster were stuck and would not come out of the cylinder. I tried putting it in a vise and using leverage to break it free, penetrating oil, compressed...

    1971 FJ40 Rear outer wheel bearing race removal

    Oops... got carried away with the angle grinder while trying to remove the rear outer wheel bearing race. Got the race off, but slightly scored the axle in the process. Anyone have this happen to them and did it create any problems? I think it should be fine, but I figured I'd get some input.

    71 FJ40 Rear Drum Brake Question

    Finished my knuckle/brake rebuild and starting on the backs. Is there an easy way to remove the backing plate? I would like to paint it up, etc. Correct me if I am wrong, but after reviewing the FSM, it looks as though I need to drain the differential, remove the pinion shaft, slide the...

    SOR replacement wheel cylinders for 71 FJ40

    I initially tried to rebuild my wheel cylinders on my 1971 FJ40. After removing them, I discovered the previous owner did not have any left-handed cylinders. At that point, I decided to get new replacement cylinders from SOR. I thought I was headed down the home stretch, until I tried to...

    I've removed the drums, wheel cylinders, axle hub face, locking nut, lock washer, inner adjusting nut, claw washer. It is my understanding that the hub should now slide off of the spindle. However, it won't budge. Am I missing something? Since I haven't done this before, I figured I'd...
