Id say get a new switch and go from there.

I would find both off the same generation truck to make it less hassle.

Under hood temps bein too hot or fuel line too close to the motor is what causes it. What happens is the fuel gets so hot it boils and turns into a vapor and starves the motor for fuel.

Not on all of em my bronco has the same pattern as the a 435.

Put new rear springs on the bronco, swapped in a 3.00 pumpkin in the rear axle, pulled the front shaft and changed the speedo gear. Next up is to lift it but that can wait for another weekend.

Check the filter if that dont fix it id say vapor lock. The fix for that would be either an electric fuel pump or a higher pressure mechanical pump.

The T18 in my bronco also has a granny so it could be either one 435 will have an aluminum shifter housing and T18 will be all cast iron.

Pull the axle out along with the carrier and mark the bearing caps wich side ya pulled em out of then get a pry bar and pop the old seals out if they dont come that way put somethin through the other tube and smack em out that way. To put em in get a broom handle and stick it through the axle...

Thanks guys. Havent been able to post much cause of work but I try.

Is it just me or do I not see any rear springs.

You can get a new lens for about the cost and hassle of tryin to buff the old one.

Got the other half of the lift kit for the bronco today gonna be puttin that on after I finish the rear axle.

Changed out the rear springs on the bronco next weekend its time for the rear axle. Gonna swap in a 3.00 pumpkin, pull the front shaft and change the speedo gear for milage in the summer then winter the 3.50s will go back in.

Be better to do a 5 speed swap.

I wouldnt recommend draftin becasue its dangerous and it pisses drivers off and ya might end up with a face full of gravel.

The quad I have on my 72 works great but I bought it brand new so that might make a differnce.

Yeah still got it what do ya need again?

Thats just who I was gonna suggest theyre out of Salt Lake and ive bought a couple from em. One was artificial leather thats in my 72 and has held up great for five or six years but is startin to show its age where I slide in and out of the truck. Another I bought that was a cheaper Dura EZ care...

To get one done in the bronco was 195 with a new locking bead but they were able to re use the old gasket its also got the blue tint strip on the top of the glass so that raised the price some.

Id grab a LP and see what happens if ya break it then youll know.

Id just suck it out as well unless youre gonna rebuild the whole axle then id drill a hole and tap it.

Painless might have one but I dont know for sure. Theres another place that makes em but I cant redall the name.

Take the spindle off the knuckle, then put the axle in carefully so ya dont ruin the seal, then the knuckle, then the spindle.

Ill have to swap the bulb out and see what happens. Thanks for the info.

Supposed to be a parking brake warning light the one on my 72 hasnt ever worked.

Well I can give ya a ballpark with 33s, 3.54s and a 4 speed in my 86 it turns 2000 at 60 so your probly pretty close to that.

Tyler yours aint full time 4wd is it?

You talkin in town or highway. I can get almost 11 with mine 400 2bbl 4spd and 31s havent looked at the tag on the diff but id say probly the same gearing as well.

To add to Bens post 3.5" means its either a 352 or 360 3.75" means 390, 406, 427 and 3.98" means its either a 410 or 428. To verify which exact one it is youd have to pop a head off and measure the bore but thatll give ya a ball park idea.

Id rent a trailer if theres a place where you live that does it.
