Hey, I'm new to the board and was wondering if anyone else had the same issue. Merace19 posted up some info from mycarstats.com that have me a little worried.

I have a bone stock 2007 Double Cab SR5 4x4, manual, w/limited slip that I used this past weekend to tow a sailboat. I had the truck on the ramp with a 4,000 lb boat. The ramp was completely wet and the stock tires weren't hooking up in 2wd, so I thought I'd try 4wd from a complete stop. I ended up with smoke coming out from under the center of the truck. 4wd still seems to work afterwards, but I never had this happen before.

I've also been smelling burned rubber from the truck on occasion before and after this incident and can't seem to track down the cause.

I'm inept so suggestions are greatly appreciated.

So what you'r saying is that when you tried to get up the ramp in 2wd you were spinning the tires, Right?

Then you put it in 4wd and pulled out the boat, Right?

If this is true then there may have been tire smoke stuck under the truck untill you got up and air blew it out. The tire smoke may have been there from when you were in 2wd.

and how many miles on the truck? Could just be the center support bearing breaking in.

how much were you riding the clutch i have seen people actually smoke their cluch before trying to pull there boat out of the ramp i am not saying that you did that but it kind of sounds that way. when that happens the smoke does seem to linger around the bottom of the truck. but it really doesn't smell anything like burt rubber

Never heard of or experienced that before. If a bearing of any kind smokes, it's bad. They don't smoke while breaking in.

It was sounding like clutch or tire smoke, but then I read the part about you having smelled it before. And as far as smelling it since, once the truck interior has been aired out, you shouldn't keep smelling it.

Were you using low range while in 4wd? The reason I ask is, if you weren't, maybe you should have been. It could be possible that there have been instances where you used 4wd before and after, as well as on the boat ramp, where the amount of torque needed to turn the tires in 4wd was enough to cause excessive slipping and overheating of the clutch in high range. This would be aggravated by both towing the boat and going up the ramp, and would explain the smell and smoke.

A burned clutch would smell more like overheated brakes, not rubber. I can see how it could be mistaken for burned rubber, but the smell is different.

Just in case the smell is burned rubber, you might want to crawl underneath and make sure that no hoses or wires, etc. have somehow managed to come loose and contact the exhaust.

My guess is that it's clutch smell, and you mistook the smell for burned rubber.

Sounds like clutch. Smoked mine a couple times wheelin same thing happened.

I agree, it was your clutch. That'll teach you to put it in 4WD next time you're on the boat ramp.

Lesson learned I guess...

its your clutch, guaranteed. Sounds exactly like what mine looked like once when i smoked it out pulling a heavy load uphill. if you were riding the clutch then it wasnt totaly engaged or disengaged causing it to burn. If you werent riding the clutch then it was just slipping because there was too much load on it. Either way id be cautious now because you only get a couple of those hefty clutch roasting sessions before it pops completely.
