Truck jerks when i come to a stop

OK, so heres my problem. When I am driving and I slow my truck down to a stop, If I slowly release the brakes my truck kind of jumps ( feels like its coming from the hood.) Should I be worried? Also, how would I fix that. Thanks!!!

 

I'm just throwing this out there and I'm probably wrong but are your parking brake cables ok and releasing the brakes or broken/seized and stuck on?

 

Sounds like axle wrap. Basically the leaf springs are worn out and when coming to a stop it allows the axle to rotate a bit. When you release the brakes you're releasing the tension hence the "jerk" feeling. It can happen upon slowing down as well as acceleration.
It can be fixed with new leaf springs, or an add a leaf to add a little strength back into them.

*at least that's what it sounds like*

Are your leafs pretty much flat, small arch up like a smile, or do they have a frown shape?

Probably this. First time my wife drove the truck she thought someone rear ended her.

 

Axle wrap

 

Grease your drive shaft

 

Specifically the splines. Good call.

I bought my 99 new with an A/T and had that issue from the beginning. When I came to a stop and let off the brakes the back end would sit down and clunk like axle wrap that others mentioned in this thread. I took it to dealer and they couldn't find anything wrong. Years later I changed all of the vacuum hoses and it went away! I believe one of the hoses going to the 2 transmission solenoids had a sharp bend and was choking off vacuum so it wasn't down shifting properly. It has been this way since the factory. These are the 2 solenoids on the left side of engine compartment behind the battery. Also, changing all of the vacuum hoses made a big difference in performance. It's like doing a tune-up.

 

Interesting. Good to know.

 

Where you able to find the issue? I am experiencing the same thing on a 2017 Tacoma TRD Off-road, automatic. It mainly happens during the first, or second, stop of a trip, for the day. Afterwards, it goes away. Really strange. I thought, it might have to do with fluids in the front and rear differential, or transfer case, but they are fine, at correct level. Axle joints have been greased, as well. The issue was mostly noticeable on cold days, in winter (for about 2-3 years, now). Now, it happens almost every day. I have tested it while coming to a stop, in 5th or 6th gear, to see what happens. The jerking does not happen in a higher gear. Wondering if it is related to transmission, or fluid level in transmission, as occasionally, the jerks seems to come from middle of truck. Mods. that could be an issue is changing I did of front and rear differentials to a higher gear, 1-2 years before this started happening. But, not sure if related to that. Would appreciate any advise. Thanks.

 

It is probably not axle wrap, but it is the slip yoke in need of some grease. It is more simple to try pumping some grease into the fitting near the rear U-joint. Just don't over do the grease because if it is too full it won't be able to slide back and forth.

 

Thank you for the reply. I will address that and see what happens. Will post a reply with results.
