Burning smell

[P1TBU11]

Since I've moved up to 35s I've noticed a burning smell ocassionally. I can't find anything rubbing. I've recalibrated for tire size. Anybody know what the problem could be?

did you regear at that time? could it be gear oil?

 

[P1TBU11]

Didn't regear. I did change differential oil and motor oil but it's been prolly 3000 miles since

maybe you spilled or kicked up some oil onto the engine/exhaust manifold when you did your oil changes. takes a while for that to burn off and will smell for a while.

Why would I only smell it some of the time?

When the oil heats up it expands. Doesn't happen all the time. Check your breather tube and see if it is damp or oily. That's probably what it is.

Does it smell like burning rubber? Check your toe alignment setting.

 

[P1TBU11]

Kinda. I had it aligned not long ago but my wife picked it up for me and didn't get any info from the shop.

What OverlanderJK said.

Also, If you over fill your dif the oil can find its way back out. Just something to check.

What does the burning smell like? Rubber? Gear oil? Something metal or plastic?

 

[P1TBU11]

It smells kinda like a vehicle that's running hot. But it's not running hot.

I'm gonna check my exhaust and breather tubes on my days off.

I had a rubber burning smell for a bit then later figured out it was some rubber skid marks that I made on the exhaust pipe after pounding the Y-pipe tight after installing exhaust spacers. I hope this helps but considering it smells like it's running hot it probably won't.
