Finding a matalic noise after bump in road.

Hello again,, 2012 new Toyota Tacoma reg. cab 2.7 4 banner 5 speed St. shift.. I have one issue with a noise I hear had it from new about 2,000 miles on her now. it's a matalic clater sound say if there is a hump type of bump that goes all the way acrossed the road front wheels axle goes over fine then as soon as the rear wheels go over I get the noise louder with the windows down..Sounds mid to back of truck.. I checked all wheel lugs also shook the hell out of the tall pipe and muffler all the way up heard nothing.. Does any oners have this that can point me in the right direction.. Thanks george

 

Sounds like you've probably checked this, but could it be your hitch? (if installed)

 

Thanks No hitch.. But ya sounds like that..

 

Sorry but reposting this here as it makes sence to me..

I have some noise I posted about just a bit ago and decided to have a look see.. Please I don't have a work shop manual for this truck yet.. just about every thing I put a wrench too I found lose or way lose.. heck even the U bolts holding the rear axle to the springs were reticules lose.. I don't know the specs on how tight things should be so I limited my tightening to body and some suspension components.. I been working on cars trucks for well over 40 years so I know about how tight most things should be.. Ya even the wheel lugs were lose.. At least the specs for them are the owner's manual.. some were as low as 20 ft lbs and as high as 70 ft lbs.. tranny mounts were almost hand lose cross member was also darn lose.. What gives are they on crack? Please if anyone can post the suspension and body torque spec's please post.. Thanks George
P.S.
2012 tacoma 4X4 reg. cab 2.7 with a St tranny 5 speed.. About 2,000 miles on it.. Take it back and have the dealer go over it.. I'm not that nuts!! Darn Munkys! LOL!! George

 

I plan on going over the midel to the front today as I still have the noise.. George

 

Sub'd for torque specs if someone comes through

 

Same, not the first time I've heard of loose nuts and bolts. Guess I need to check mine...

Thank you for that info!

Ok was under the front today grabbing pounding on and pulling on things.. Only thing I could find that could be the sound is coming from the inner sides of the front axle shafts where they go into the front differential. This could be normal for all I know with Toyota.. There is enough wiggle on the inner CV joints if that's what Toyota even calls them. About 1/32" to 1/16 of play or movement to them and if I hit this part with the heal of my hand I can hear a metallic noise.. is this play or noise normal? It's a pain over dirt washboard roads. It's the only thing i can really find.. my back is just to bad today to get a wrench on every nut and bolt today.. but I do think it's something I may now have top live with.. What do you guys and gals think? thanks a bunch! George

 

98tacoma27,

CV joint is ok but axle into diff. can side it slides in and out very little I think that's ok.. No, I'm describing a up and down movement. I mean it's round so you could physically move it like that all the way around.
I guess the best way to describe it is to grab onto the CV just the inner side of the boot where it goes into the front diff or axle housing it a metal part that the boot clamps too. Kind of a octagon shape and pull push on it up and down .. Not like sliding the hole axle and CV just in and out.. Hope you know what I mean.. George

 

Maybe what I'm hearing is the inner axle splines slapping up and down when going over bumps. I wonder if the axle spline was greased before install? Any other known places to look? I think my rear springs are still not making noise. Sound it tricky.. 2,500 miles on it now but noise was there when going over bumpy or washboard roads. Get it on single bumps too if there big enough. Thanks! George
