Used 4Hi on pavement...what now?

Guys, noob here needs some advise. I used my 4hi for the first time today on dry pavement. I mean I drove at least 5 miles including making a couple turns. I felt something was off when I was pulling on my driveway today as it was super hard to navigate the car in low speed in 4hi. I then found out I wasn't suppose to use 4hi on pavement...ever. Question is, have I screwed up my Tacoma? Should I bring it in for a check up? It only has 3k miles on it btw. Thanks for reading and I appreciate any advice at this point.

 

It's fine. Just don't make a habit of it.

 

Check your CVs at most. I wouldn't worry about it.

 

Fine

 

Ditto. It's fine.. just don't do it going forward.

 

You're fine but many people do early fluid changes in their diffs to get rid of break in debris and switch to synthetics. I guess if you were really concerned you could think about doing that, since many people do anyway. If you're not particularly OCD, just wait until the maintenance schedule tells you it's due.

 

Sorry to jack the thread but ive got a question.
In the winter time, to be on the safe side, using 4hi on potential frozen road is bad as well?
For example, probably a whole different story but like my old Audi A8 had full time 4wd. Why not Tacoma?

 

I drive mine 10 miles a month on the road since I'm yet to have the time or a place to offroad. Just don't make a habit of making sharp turns

 

I won't. I used it once on wet pavement before but I don't even think that's advisable.

 

Snow and ice is fine. That's why I have a 4X4 in the first place.

 

I have heard that because it is a part time 4wd, you shouldn't use it unless the road is slick.

 

As long as it drives okay when you put it back in 2WD, I wouldn't worry about. I wouldn't go telling the dealer that I ran it in 4WD on pavement though. According to the manual you're supposed to run it 4WD for about 10 miles every month just to keep it lubed up, but I don't always have the time to find a dirt road. So I run mine in 4WD on the pavement occasionally, but I generally don't make any turns while it's engaged.

If the road is snowy or icy, that's fine. As long as the wheels can slip a little as you're turning, you'll be ok. Your Audi had a different type of 4WD, where the transfer case allowed the necessary slippage.

 

Yse but what about to use 4wd on pavement to be on the same side? Potential frozen highway drive and snow city drive.

 

4hi on a frozen road would be fine IMO. If I'm slipping in 2wd, I think it's safe to say 4wd won't fuck up anything.

 

That makes sense... Is this mean if you install aftermarket(if there was one) LSD, it will be fine?

 

So I am confused- don't drive in 4h on dry roads. What about wet, slick, snowy roads....... 4h is good then ??

 

Not necessarily, an LSD usually just prevents both wheels from loosing traction at the same time. You'll always have "some" power to one of the two wheels with LSD. LSD doesn't in turn, allow slippage in the gears. When turning your wheels need to go at different speeds, but the 4WD system is trying to make them turn at the same speed. That causes excessive pressure on the 4WD parts, and with enough pressure, things will break. Vehicles with ALL Wheel Drive like your Audi A8 or Subaru's usually have some sort of clutch system in their transfer cases, that allows the slippage to occur.

 

Just don't do it again. You could seriously fry your transfer case and front driveshaft it's only meant for slippery conditions

 

Yes.

Basically, use it when there is a chance that your front wheels can slip. Otherwise leave it in 2WD. Never on dry roads, unless the wheels are straight.

 

As long as your steering wheels can "slip" when they are being turned you should be ok. Dry pavement usually doesn't allow the wheels to "slip". When pavement is slick, not necessarily just wet with water, but with snow or ice, there will be enough slippage to be okay.
