Feels like I'm getting rear ended when I stop

i have a 06 Tacoma sport with 80000 miles ...most of the time i come stop at a red light it feels like somebody hit me from behind.. What can it be the transmission? I never done a transmission flush

 

Do you hear any 'clunks' when you put it in drive or reverse?

 

Completely normal. My 2015 did that the day I drove it off the lot.

 

How's the carrier barring? Check for play in the driveshaft when you're parked.

 

Sounds like axle wrap.

True. But many trucks did/do it stock.

 

Well when I take out of park into reverse or drive I have to put a little pressure like if I'm not pressing good on the breaks

 

Ok I will , so it should move at all? Or rotate a little bit?

 

Don't rotate it. Just push up on it. If there's more than an inch or inch and a half of play, that's your cause.

 

And if it's that is it something I should be worried about ?

 

Not at all. You should just replace the bearing.

If it's not this, it could be number of other things. The description you gave was kinda broad.

 

Driveshaft slip yoke binding, lots of Toyotas do this. I've only ever been able to fix it with a new driveshaft. I wouldn't worry about it.

 

I'd make a wild guess that your carrier bearing and u-joints have never been replaced?

 

Mine kinda makes a nose when I take it from park to drive or reverse. Grindy or cranky noise. At 28k miles had it when I bought it at 20.

 

That's something completely different and should be looked at by a mechanic

 

I had that on my 4Runner, when I bought it new. I got lucky, there was a TSB for driveshaft, replaced under warranty. No problems since then.

 

Its only when it's in a cold start once it's warmed up there is no noise or slight grind noise. I'll ask my mechanic at work on Monday working for expierence in a shop. No idea what it could be but everthing else runs okay beside the shocks that need replacement soon. No idea what causes the slight noise when starting cold and switching from park to reverse or drive it's nothing barking loud that made me worried or anything just a slight shifting the gears sound.

 

So I when's under my truck and is this what you were talking about? Cues I push it up and it does move a little bit maybe half inch

 

Nope never

 

I can't really tell by the picture but just try to push on the actual driveshaft itself. The long thing that goes towards the rear diff.
