This make sense??

9 posts in this topic

2005 F150 that is 'stuttering' when making a left turn. 95 K on it. Friend's rig - the mechanic told him that the oil in the differential is worn out and that it needs to be replaced or an additive put in. 4WD. I'm sure the fluids - differential and trani need servicing but I don't know enough about differential's to know if this fluid idea makes sense.

Thanks for the advice.

These trucks have a limited slip diff in them, and they have clutches in the rear diff to allow slipping on turns, what you are more then likely feeling is the clutches chattering, and this is very comon for this truck. The correct fix for this would be to replace the clutches inside the rear diff, and install new fluid and additive to the rear diff.

But what I would do before this, if the truck was mine, I would try adding a bottle of friction modifier to the rear diff before spending the money to put the new clutches in it.

Yep, the first step in freeing up the clutch disks/plates is to add the friction modifier additive, drive for about 100 miles and see if it goes away. If it does not, then try a full fluid change with the additive. Then worst case if an O/H of the carrier.

9/10 out of ten just putting the additive in will fix it, but it is a good idea to change the fluid, but it is not cheap.

Good luck!

This I have seen work wink and more than twice grin Not a guarantee, but the majority of people who tried it had a good result. 4WE can check, but I swear this was a service bulletin/procedure to try first right from Ford.

Did you forget to put the additive in? grin

That is almost a guarantee in it’s self it will happen and for surely not fix it. Most times this was the case when trying to cure this. The customer or someone did a fluid service and did not put the additive back in.

The only bulletin I know of is the ones to replace the clutch pack assy. and add the friction modifier. I just checked, and didnt see any ssm's or tsb's like that.

There was an internal bulletin from Ford to add some friction modifier to the auto transfer cases for chattering, but later found out the auto 4wd clutches did quit chattering, but the clutches wouldnt last long with the additive in it.

    •   I would definitely get the one with the Pheasant plowing attachment! Beats walking the fields!
    • Never getting rid of my Suburban. Just looking for a new toy for hunting etc. that I can drive down narrow dirt roads up north. Another reason why I would rather buy a slightly used one so I can use it without worrying about putting a few scratches on it. Those side by sides look like fun but you have to haul them around and cant drive them everywhere. And they just aren't built to take what a Jeep can. Always kind of liked the looks of Jeeps and being able to remove the top in the summer is nice to. Would definitely want a hard top to as the soft tops aren't to good for MN winters. I'm sure the newer ones have better heaters than the older ones as I remember back in the day guys were dressed like they were snowmobiling while driving their Jeep. And scraping frost off of the window to see.
    • I went through the same thing. I had ATV's at first then bought an RZR. It was fun but honestly the quality for the price is pretty bad. You can go up to a Can Am but then the price is even worse. So a few years after I sold the RZR I got the itch again but then started looking at the Wranglers and ended up doing that. I bought a 2006 with the 4.0 and after that and buying a used 6.6' plow I was into it for less than 13.5k and can drive it everywhere.   I have the hardtop on mine. I just take it off in the summer and drive it when it's nice. IMHO it's the way to go but you need to watch out for ones that are rusted out. I take the doors off, the top off and drive around sniping gophers, head to the lake or just cruise around. I like the 32" BFG KO tires.     
    •   What's a big guy like you going to do with a little SUV?  Your still keeping the truck to pull that new trailer right?
    • Good luck, have fun and stay topside this time of year.
    • Did you have to sand in between coats of lacquer? I was going to use a pre catalyzed lacquer for a little more durability, but it seems like it would take forever to get in all of the grooves. 
    • Some of the older ones had a 4 cylinder. Think the new ones only have a 6 now.
    • White pine needs bud caps to survive.     DNR had this publication you might find interesting managing_woodland_deer.pdf   Here is another link.... from extension   http://www.myminnesotawoods.umn.edu/2007/04/minnesota-woodlands-and-wildlife-strategies-and-species/   Balsam fir and spruce are good if we ever have another bad winter....
