Slight bump when coming to a complete stop

[PK470]

Hi,
My wife has a 2004 Toyota Sequoia and it recently started developing this weird feeling when approaching a complete stop. There is some type of mild bump/ kick right after stopping. It feels like the front motor mount is going south but again I remember reading somewhere on here an issue regarding the rear drive shaft/ axle on the Sequoia needing some type of lubrication. I can’t find that thread anywhere. Could someone point me to the correct direction please? I would like to know exactly what to do.

As always, thanks in advance.

If the HVAC selector is on defrost or the A/C is on it could just be the idle up circuit bumping the idle a hair right when you come to a stop. My 05 Tacoma does this and so did my last one. Only when the A/C compressor is in action though. Pretty common on the Tacoma's from what I hear but it's a strange feeling having it wanting to bump forward a hair just after slowing to a complete stop.

Have you checked ujoints lately? That can be an early sign they are going.

Or if possible, grease the slip yoke on the rear driveshaft, as well as all of the grease fittings for the U-joints, and see if that works. I am unsure if your Sequoia has greasable units, but it would be good to check. It cured a clunk in my driveline.

grease the drive shaft and clean off the slip yoke if it has some rust build up. some medium emory cloth will take care of any rust. also do the front as well

This sounds like what my new to me 06 Sequoia is doing. At least I hope so. I've had driveshaft slip/bump in other vehicles but this is a little different. Did the OP get it figured out?

Crawl under there and take a real good look at the cross member where the trans mount bolts up. You may find missing bolts and cracks which would show up as rusty lines with peeling paint. There's a TSB for the 05-07 models and a replacement cross member is available that doesn't include the weld-on frame brackets. If you need a copy of the TSB, let me know.

My wife's 4-Runner was doing this. Sometimes it felt like I got re-ended, and I would be looking if I got hit. I heard about lubing the slip yoke on the rear driveshaft. Since keeping it properly lubed-it hasn't happened again. For some reason, if you take your vehicle for an oil change you have to tell them to lube the drive shaft or they don't do it. This I cannot explain!

First time looking at a tranny mount so hopefully I got it right, but the tranny mount at the center of the crossmember looks pretty solid. I looked inside the crossmember as well and found a few hidden bolts.

I read elsewhere that it may be the tranny shifting from 2-1 at a stop, causing it to lurch from the lower gearing in 1st. Does this make sense?

This is the way to reduce this feeling. The grease takes up the lash and smooths out the "bump". Ive never seen it develop into a problem.
