Newb (and mechanically challenged) with a 2009 SR5 Crew Cab, 6500 miles.
Last week, the truck started making a popping noise which sounds to be coming from underneath the truck, in the area of the right front wheel, but the noise sometimes seems to travel toward the rear of the vehicle.
Most of my driving is on the freeway, and the noise so far has only occurred on straightaways, at speeds greater than 35 mph. It doesn't happen whilst turning or going over bumps in the road.
It's usually just a single "pop" sound, but sometimes occurs in clusters of three or four.
I've crawled underneath, looking for something loose or obvious, but everything seems to be as it should.
I read some of the posts in this thread: http://www.tacomaworld.com/forum/sus...ing-noise.html but I'm not sure the advice there would apply, since my noise does not occur while turning.
