    Ford trac lok no friction modifier

    Got up early and took the solid spacer out. Brought turning resistance to 15 inch pounds.......still has the 2 spots that bump bump bump. Beam indicator bounces like going over a washboard on a dirt road. Crazy.....spins smooth till you get around the 10 inch pound mark and from there it's...

    I assume this pinion support will work? https://tomsoffroad.com/products/ford-9-inch-pinion-support?srsltid=AfmBOoqnr01qXaXNZ67hr2yy-M3gIlD-kGmhHUxV-m7XvfRu5eI9OsOgbEc&gQT=2 Tim

    Ford trac lok no friction modifier

    Well I'm no expert but I think the pinion support is warped. First indication was the new races didn't set flush. I drove them home and started playing with preload. Started where I was with the crush washer and that gave me 10 inch pounds but here's the thing..... When spinning the pinion...

    Wealth of knowledge you are Sir. Had some younger eyes look at the casting number on the pinion support. You are correct..... 4 6 6 8 A Those 6's look like 8's to me unless I get it in the perfect light. Might be time to get thicker glasses. :) That saves me $13.99 plus tax.....and I say...

    Ford trac lok no friction modifier

    So I found the inner and outer bearing and race was the same on this pinion. Timken M88048 "made in USA" stamped on them. All the local parts stores show different part numbers for inner and outer bearing. Races are the same P/N. Inner bearing is double the price as the outer? Marketing or...

    DITTO on the torque to yield bolts I picked up the solid spacer with shims for $22.47 delivered. Crush sleeve is around $8 local so yep, I over spent. I'm in the ditch on the fix it cheap by just adding friction modifier. If the case is in good shape, I'm going to put in new clutches in the...

    Ford trac lok no friction modifier

    I like a solid spacer for ease of setup and the ability to change seals later on with just a quick nut removal.. Seals are not what they used to be.........Seems failures are more and more often these days. Will have pinion bearings this PM. Just took the old bearing off the pinion (love my...

    What are your non-negotiables?

    Each rig is different......but Borgeson power steering along with adjustable track bar, adjustable steering link and track bar drop bracket were musts on my rig. Upgraded front brakes to disc is top at the top of the board too. Tim

    Ford trac lok no friction modifier

    I can't find a casting number on it. Says FoMoCo....4206 with a E all in a different spots. All that's on the ring gear bolt side. Nothing on the other half that I can find. It is cast iron.... Took the pinion apart and removed the old seal. Replaced the crush washer with solid...

    Ford trac lok no friction modifier

    Pinion 12 teeth, ring gear 39 so 3:25 ratio. 28 spline axles. Got the pinion assembly out. It does have a "hitch" when spenning it by hand. Bearings are tight as in no movement but clearly something is binding. Pinion hat is C5AW-4688A Housing is C7AW-G So really you're saying to just buy a...

    Ford trac lok no friction modifier

    I would like it to act like a LS should. I considered dropping in a eaton truetrac like I have in the Bronco but this LS and gears look new and I don't have $500 in my pocket right now. It does lock up and spin both wheels. It unloads like a spartan locker around some corners. Bang and...

    Ford trac lok no friction modifier

    First this in not Bronco but since it's Ford 9 TL related I thought I would post in the tech section for others in this situation. Long story short, my 1969 Mach 1 BB 390 car has always acted up when cornering. It's not driven that often and I figured it was just an aggressive locker. Well...

    AGM or LiFePo4 battery to stop as many battery replacements?

    Bad voltage regulator maybe......disconnect the alternator.....see if it goes away. Tim

    AGM or LiFePo4 battery to stop as many battery replacements?

    Draining an AGM all the way down will require a special charger to bring it back. Some AGM batteries can be "tricked" into charging with a standard charger once they're dead others can't be. I run a few AGM's on my rides including my bass boat.. Sams club Duracell brand. Good stuff. East...

    clean-out just heater core

    If it needs a flush....it needs replacing.....You're just kicking the can down the road. I mean I get it....but summer is the time to do this. Remove the heater hoses and connect them together. That way you can drive around this summer with no heat and work on it as you can. It's not that...
