I hey an 02' tacoma 4x4. It's got 195,000 on it, tundra brakes, aftermarket alloy wheels, new wheel bearings/ good ball joints and tie rods, a new steering rack, and rancho quick lift struts. I do a lot of driving, about two hours or so everyday, it drives smoothly with no problems most of the time. However, there is an intermittent pulsation when driving, and the brakes pulsate VERY VERY much. It will stay for 20 mins or so, then everything will be fine. It doesn't happen in any specific gear or at any speed, i suspect it might be the front differential? But i really don't know. Again, it will drive fine for a while then a slight pulsation in the front end accompanied with a bigass brake pulsation, then will randomly go away. Any thoughts or suggestions? I appreciate anything

 

are you the kid with the 18 inch bling bling rims with 37's on IFS?? even if your not. can u try another set of tires and see if you still get the vibration?

 

No wise-ass. I'm not. They're 275-65-r18 and no i don't have another set of tires. But They have been on the truck for several months and this didn't happen during that time period.

 

weird. have you rotated the tires? i got the poly steering rack bushing kit and it helped alot with bigger tires.. sorry man. theres a gray 4 door around with 37s on ifs. kinda funny..

 

curious to hear an update on this. I just picked up an '02 Tacoma, relatively stock. pretty shocked (disappointed) to find that my old '87 actually feels smoother at 70mph than the '02. at first thought it was that center support bearing, but most of what I'm reading is saying that this is a common, known issue? I'm still on my way home with it, but got the ridiculous brake pulse, too. just figured it was warped rotors. pedal feels super tight and sensitive, as well.

 

Did you ever find the problem causing the random vibration?
