Hey, I have an '04 Tundra Access Cab Limited which I recently got a couple months ago. It's a nice truck, I got it for nothing from a relative with only 98k miles on the clock. I've heard this annoying ticking/rattling noise only when I step on the gas, and it seems to be coming from the driver's side. I've read that a lot of first gen tundras have issues with exhaust manifolds which have the tendency to crack, but i'm unsure if its the issue. I had to get the truck inspected to get permanent tags and the shop said there weren't any exhaust leaks, unless they aren't able to detect cracked manifolds that easy. I'm wondering if there's any easy way to rule out cracked manifold vs. something else. Also have been reading that some Tundra owners have fixed the noise by replacing a seal on the steering column in the firewall. Apparently these seals can get torn or broken down over time causing engine noise to be directed into the cabin. Have any of you guys had luck replacing the seal on the steering column, and did it fix the problem for you? Is replacing the seal worth trying? Thanks in advance!
