4x4 question

[Eagle2006]

Hi guys! so thank you for all your comments on my other posts. We’ve updated the Module and I haven’t had any more crazy noises so fingers crossed. It’s in the shop now for the brake replacements. Parts finally came in! After that I’m just waiting on the rear window and all the leakage damage. Blah.
So I don’t do any off reading or whatever really. The only time I tend to use the 4x4 is on really blizzard-y conditions.
This winter tho, I was ice fishing and I still had the factory tires on the truck and they are garbage lol So I got stuck in like 3 inches of snow haha anyhow when I got stuck I already had it in 4x4 high which I usually do when I go out into the lake. Something strange tho that I’ve either never noticed in another truck or didn’t know this happened OR there’s something else wrong with this truck lol so when I was on the gas trying to get the truck to move while someone was pushing by hand on the tailgate- I would stop accelerating so we could take a break right? But the tires didn’t stop spinning. It also did it to me this morning. Where I park is really icy right now so I started out in two wheel drive to get it out of the snow but I wasn’t moving so I put my foot on the brake and pushed the button for 4x4 high. But it was weird- it was like my wheel hadn’t stopped spinning and it did a little kind of jerking motion and I could tell the wheels were moving but my foot had never left the brake. The traction control comes on whenever the truck is on so it was active. Is that what this is? I’ve never had a truck do that to me in four wheel drive before. Anyhow, is this normal? I always wait until I’m at a full stop until I do anything- move it to park or reverse whatever. Thanks!!!

You can even go into 4x4 high when you are traveling like 50mph, you only need or should stop when you go to 4x4 low. You just want to make sure you are on the same surface, you don't want to have some wheels on cement and some on dirt. The more you use it the less it should jerk.

Read the manual but with most trucks it works best to start in 2nd or 3rd gear so there is less torque applied to the rear wheels. The anti-spin option only activates the ABS brakes so they apply to the wheel and slow it down and allow the differential to apply more power to the slower wheel. It is not by any means a locking differential which costs an extra $50 for the truck.

You might want to invest in a pair of the traction tracks / mats that you can put under the tires in such conditions. These also work well in sand and mud.

I see! My buddies ford has the locking diff and that would make sense as I’m used to older trucks that you had to get out and lock the hubs. Is anti-spin the same as traction control? Thank you for your reply!

Thank you- yeah if I’m travelling and I need to throw it into 4x4 high, I’m still kind of old school and I like to shift into neutral and then into four wheel drive lol I don’t need to do that anymore but... also my friend told me not to shift into four wheel drive while accelerating as well so I don’t do that either. It looks like I’m keeping the truck now (trade in just wasn’t worth it) so I’ll still baby it, I’m sure lol Need to learn to enjoy it too I guess! I doubt I’ll ever use low but never know. Thanks again for your reply and I’ll have to invest in some decent tires for next year!

I’ll go find the manual lol instead of asking you guys questions that I can probably answer in there! Thanks!!!

Next winter, better tires. You’ll have far fewer issues.



Not too sure what’s inside the 1/2ton anti-spin diff.... on the bigger trucks we have a plate style lsd.

When its very icy, the truck definitely has enough torque at idle to turn the tires while sitting still. It also requires a lot more pressure on the brakes to stop the tires turning because they don't have the extra drag from the pavement to help slow them down. Could be that you just didn't apply enough pressure or wait long enough for the wheels to stop moving before you shifted. While you can shift on demand up to like 50 mph, when you shift into 4wd and the tires are turning at different speeds, it can clunk or grind some. I would definitely consider some better tires if you are in an icy snowy area.

There is enough torque to overcome the brakes if you aren't applying enough pressure, as described above. I once owned a diesel Chevy that I had to shift into neutral when I wanted to stay stopped at a red light. The torque of the engine was high enough to overcome the rear brakes, and would literally push me into the intersection. It became second nature for me, but was dangerous if anyone else drove my truck.

Those stock Goodyear SRA's are crap in the snow if that's what you have. I had nothing but trouble with them on a 2015 Tradesman I used to own. The Falken Wildpeaks on my new truck are fantastic, especially for stock tires. But for best results, nothing beats actual snow tires for winter driving. Even with those, some brands are definitely better than others.

Thank you! I never knew that. Explains why my tires were still spinning lol I’m going to keep these tires on for the summer and buy some more come fall. I liked the wranglers on my last truck, might go that route again. Thanks again!

thanks for your reply. I wasn’t aware about the tires still being able to spin. That’s interesting. Yeah I’m going to keep these tires on for the summer and get some new ones come fall. I liked my old wrangler tires so I
Might to that route again. Thanks again!

Anti-spin uses the ABS braking functin to apply braking to a wheel that is spinning faster than the one on the opposite side of the axle. On sedans it has been called "traction control" and it is better than nothing with a 2WD rear drive car.

I have had many 4WD vehicles and it was not until 1989 that I got my first pickup with limited slip that used clutches. I was surprised at how much less I needed to shift into 4WD with the LSD when going uphill on gravel roads.
