1998 T100 4x4 xcab, 54k miles
I have a front end popping noise that happens when braking firmly (not the steering stops). The Toyota dealership has spent hours in attempt to diagnose but failed. They checked all they could think of including brakes, ball joints, upper/lower control arms, engine mounts, cross members, etc... The pop is audible from inside and outside the cab and seems to be located low in the passenger side front end area. You can hear it pop this shift back/resetting somewhat. The dealer's advised all was safe and to drive it until it became so bad that they could tell what it is. Well, I'm impatient and would like this resolved sooner than later. Has anyone experienced a similar popping noise that can help? Thanks.

it may be motor mounts something possible for a shop to miss. open your hood stand beside the car and have someone put the car in gear hold the brake and give it a little gas also try to check the winch plate.

I'm having the same problem, with my 07 tacoma. Had it for alittle over 2 years, and it started making the same noise about 5weeks ago. They replaced the rotors and brakes even and made sure everything was tight. Let me know if you can an answer, I'll do the same.
