This is probably obvious to your experts, but what would be the cause of a metallic clanking sound when hitting small/moderate bumps or dips? The sounds only comes when the front driver's side tire goes over a bump/dip, and it's a metallic sound kinda like hitting an aluminum bat or pole. I recently upgraded my endlinks and shocks/springs, and that didn't help. Could it be the control arm?

 

I was thinking end link broken but you say new
ck mounting of the new parts,,lowered?
look for rub marks/bare metal scrapes on sway bars-control arm

springs went on correct end of car,,its happened before~

 

Yeah, the clanking has been going on for a year maybe, and I just updated the endlinks/sways shock/springs but the sound persists.

I'll check for rub marks/bare metal scrapes on the arm.

 

Have you changed the sway bar bushings as well, or just the endlinks? Also inspect your lower control arm bushings, specifically the one that attaches the strut to the arm.

 

Let me know what you find. I have a sound from the drivers side also. I have replaced the sway bar bushings and links. This did help but it is still there.

 

I'm gonna have to jack it up and crawl under there to find out what's going on. I changed the endlinks and swaybars with the eibach kit, not sure if the bushings you're talking about jra are part of that.

 

I had a similar problem and it was the upper control arm that had a bit of play, replaced it and noise gone. The way I found out was by jacking up the car on both sides evenly and kicking the tire in the front at different angles until I heard it. Hope this helps

 

Thanks Erick for the suggestion. I'll have to get jack stands and try that out.

 

Thanks to Skirmich, my problem is solved!

The slider pins that came with my legend calipers were different than the TL ones. I also noted the upper Legend slider pins didn't float as they should--they seized for a second before bouncing back after being compressed. After replacing, no more annoying clanking on every bump on the road.

The TL has two different slider pins - A brass one with flat edges and a grey one which is uniformly cylindrical. The correct placement is the brass/edged pin goes on the lower end of the caliper, and the smooth grey one goes at the upper end of the caliper.

The rebuilt Legend caliper I bought (Rockauto, I think) had two identical edged pins. This is probably why the upper pins were catching momentarily--they're the wrong size.

Here's a helpful image from a previous thread:



And here's the original thread.

 

Hey guys is this true that our 2nd gen TL's have 2 different slider pins for the brake caliper/pistons one being slightly smaller ? Just wondering because i did my first brake job on my car a few days ago and didn't notice the slider pins being different sizes. I wouldn't want them to fail on me if this is correct.....
