added a set of MRAP retractable shoulder harnesses. Should make the trail a little safer and more comfortable than the normal 4 point harnesses.
The anti sub belt will be removed

need to paint the harness bar but the worst of the work is done

After paying $42 to refill my CO2 tank I started looking for alternative fast air sources.I thought about a Viair system but didn't think $400 was worth it.
Decided to give ebay a shot with a seller I have had good luck with in the past, picked up one of these, only bidder at $99
Heavy Duty 150PSI Portable Air Compressor 12V High Volume Extreme 35" Tires | eBay

It basically looks like a generic Super Flow MV-90
it sucks a ton of juice but is fast

Filled the empty 35x12.50 from 0 to 30 psi in a little over 2 minutes

I was recently scored a set of Trail-Gear trunnion bearing eliminators from a local guy hard on his luck.
$150, couldn't pass it up:
Image
Over the weekend I replaced my 4 tie rod ends, test drive showed everything was good to go.
I headed out monday morning to head out to the forest to run some trails with some friends over the Memorial Day holiday.
about 2 miles from the meet up location i had a really bad shimmy. Pulled over and checked things out, everything looked fine, tightened the lug nuts, no issue there. Tried again, at 35 it was bad so headed the 40 miles home never being able to get above 30 mph
So I got to thinking i could have blown a trunnion bearing on my last run and might as well start the replacement process.
Image
I did find some play in the bearings, but nothing that would account for the sudden onset of death wobble.
I had the front end rebuilt 6 years ago by a friend who needed some cash, he didn't mention that the driver side knuckle ball looked like birfield had exploded.
Image
Passenger side looked pretty good
Image
inner axle seals were is relatively good shape

it was also good to see that the Trail-gear Dirty 30 axles were still looking good after 6 years and several thousand miles.
Image

so no smoking gun but I am going to replace the wheel bearings too, swap out the steering shaft and button it up hopefully over the weekend.

Cool! Let us know how it goes and if the wobble is gone afterwards. :thumbup:
When your road comes to an end ...... you need a HILUX!.

Thank you sir.

I haven't a lot of time to get the front end back together but got a little bit closer.
Part of the trunnion bearing eliminate is to get rid of the 'stock' steering pivots.
Image
i probably could have used a vice to drive the pins out but opted to pick up a 12 ton press.
It made short work of the pins
Image

Plan is to clean up the axle housing and repaint the steering arms and knuckles.
I may also drill the stock spring mount and move the axle forward an inch or so. I am pretty sure i could as far forward as 2" with out binding my steering linkage.
