Front Diff Slip Issue

So I've asked a few people and nobody else has had this issue so now it's up to yall. This issue was occurring pre titan swap and has continued to occur after the titan swap. It didn't start occurring until I put 33s on, when I did the switch I kept using the same wheels that I had been using with 32s and the same brand that I had previously used with 32s. Literally the only changes that happened prior to this starting was the change from 32s to 33s.

When I take turns with VDC turned on the diff will start grinding while the truck starts doing it's SLIP function. I've had this happen when taking sharp turns, long curves and even had it happen when I wasn't actually taking the curve just splitting the middle on an S curve to keep a straight line. It has occurred at speeds ranging from 20mph and up. If i turn the VDC off then I don't have this issue unless I take a sharp turn at a high speed that I shouldn't be going for that turn.

are we talking about in 4x4 or 4x2 mode? When you say pre and post titan swap did you swap the diff too from M180 to M205? Does it happen on paved roads (dry, snow, ice, wet) or dirt roads or any type of road? Is your tiring actually slipping or is the sensor acting up due to tire size change.

My slip function never turns on unless I'm pushing it hard on dirt or mud. Even when I was 33's. I know there are some people who ran into trouble with wheel speed sensors acting goofy when increasing tire sizes for around corners. Which play a role in slipping turning on or off.

So far only in 4x2 I turn VDC off for 4x4 so it's never had the chance to do it. Yes the diff was swapped from the the 180 to the 205 and it does it with both of them. So far only on paved roads, again never been in the position to be using VDC on anything besides paved. It's done it on bone dry and wet roads, I'm usually going slow and swing wide when possible on snow and ice. No actually tire slippage it just sounds like the diff gears trying to destroy themselves while the SLIP light goes crazy.

This sounds like your VDC & ABLS functioning normally to me. Especially if the slip light comes on and the sound goes away when VDC is turned off.

There's no reason for it to be going off when I'm doing 20 making a slight turn hence the reason for the post. I understand it going off if i'm actually in a slip or potential slip situation but I'm not I'm turning while doing normal driving.

What lift height are you at? There are lots of things that could cause the increased sensitivity. Poor alignment is one of the biggest reasons.

This issue was occurring with only a 2 inch BL and a 2.5 - 3 inch SL that was compressed from armor.

Metzican,
I have the same problem you have described, quite a nuissance- occassionaly results in me getting stuck. Is it safe to assume both of your lockers will overide the slip warning?

Thank you,
Ed

Different vehicle, but reiterates what ryan said.

Last winter my wife had a guy hit her during a snow storm she was sitting still at the end of a road and a guy was trying turn and slid directly into her wheel with his bumper. after it every couple of minutes the vdc light would kick on. turns out when she was hit the very top of the strut abou two inches below the mount was bent. When we went around a curve the weight would shift the shaft on the strut would spin a liitle causing the angle of the wheel to change a little and it would set off her vdc and if you were hitting the brakes at the same time the abs would kick in. This was in an mdx, and I dont know if the x has all the sensors to notice the angle of the wheel changing or not. However, if like Ryan said your alignment is off or maybe an abs sensor has a problem it might be the source of the problem.

Could also be the unit bearing assemblies on either side as well. I meant to mention that earlier as well.

Alignment has been done multiple times since December of last year when this started. Not only that I've done the titan swap since and it has continued to occur. It literally started after changing from 32s to 33s nothing else changed about the truck at that time not even wheels just swapped from worn out 32s to new 33s in a brand that i have previously run in 32s.

Just finished looking up the reset and everything I've seen for it is if your ABS and SLIP lights are stuck on which isn't my issue.

Sadly I closed the page I had found before I linked to it, but I think it was on tnx. A guy did his suspension lift and got 33's and siad when he would go around curves his slip function would kick in and sometimes the vdc light would come on. Apparently one dealer told him it was something expensive like the abs controller (cant remember exactly) took it to another dealer and he said the tech jumped in and drove it across the parking lot in a straight line and problem was gone since. Might help. Might not. But its easy and free so why not try.

There are some posts on tnx about it but difficult to find. My '05 started doing this right after I put on an OME HD suspension and 33’s. There were 2 particular curves on my way to work where it happened. Slow, 20-25 mph with slight curve. Happened once or twice on highway off ramps with similar curves. The problem just stopped happening after awhile w/o me ever doing anything at all , i.e. no alignment, brakes, anything. I remember others saying the same thing. Something about the computer adjusting to different wheel speed because of the different tire size iirc.
It never happened on my '13 after initial lift and 33's or after t-swap.

Another little tidbit that may or may not be relevant. I know from researching wheels and tires for my g35, on a g35 when people get new wheels and tires that are bigger there is this whole rule on the forums about not increasing more than about 2% in diameter or it will do similar things with vdc and the abs that you are describing. It confuses the computers because the speed sensors are expecting a certain speed, but when going around curves reported rpm from the speed rings dont match the reported mph from the transmission. Some guys say it eventually works itself out. Some say it stays that way. Aince both vehiclea are made by nissan maybe they use similar systems. An increase from a 32 to a 33 is a 3.125% increase.
