ticking noise from 01 z71 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

cstm68 · 07-24-2012, 09:12 PM

a few weeks or so ago my 01 silverado with a 5.3l started to make a weird ticking noise, it only does it at speeds above 50 or so and i can only here it when passing a wall or concrete barrier on the freeway with the window down. rpm does not seem to change the noise but speed does. has anyone had this problem. i dont think its the motor but worried it could be from the tranny, its got aboyt 125k on it.

Look at the exhaust manifolds, especially on the driver's side, and look for a missing bolt head. The one at the back by the firewall is notorious for snapping off on these trucks.

That sounds like a U joint to me too. When my U joint went out it was making a ticking noise.

sweet thanks! ill throw it on the lift tomorow and check all that!

cstm68 · 08-02-2012, 09:19 PM

checked my u joints and they are in good shape, i heard the noise again today and put the truck in N and didnt change it, it almost sounds like there is a rock in the tire but i only here it at freeway speeds and ony after its been at that speed for a few miles.

I had a car do that one time and it was a trim ring on the rim.

cstm68 · 08-12-2012, 08:30 PM

could my u joints be bad but not have movement?

cstm68 · 08-15-2012, 02:05 AM

i replaced the u joints today and there was no change, i was able to get up to speed to make the noise and put the truck in neutral and shut shut the engine off and it still made the noise, does any one have any other ideas???

**truckdude239** · 08-15-2012, 08:53 AM

is it 4x4? the transer case could be going bad

clinebarger · 08-15-2012, 07:59 PM

Also check for missing brake hardware...A loose pad can cause clicking noises.

cstm68 · 08-16-2012, 12:58 PM

yes its a 4x4, iv checked all the brake hardware and its all good.
i guess ill take it to my tranny guy and have him look at the t case

cstm68 · 09-08-2012, 01:54 AM

i got the truck up on the rack today and ran it to about 60mph in the air, i heard the noise and was able to track it to the t-case, i changed the fluid and that seemed to quiet it down but it is still there, would you guys reccomend having the transfer case rebuilt or just buy a new one?

Because your catching it before complete meltdown....Have it rebuilt, These guys build all my manual transmissions & transfer cases.... http://www.standardtransmission.com/transfercases.html

Buying a NEW unit is Very expensive or impossible, Depending if you transfer case is still in production.

Took the t-case out today and to the tranny shop. He tore it apart and says that everything is fine. No loose chain or anything... Now I'm really stumped.
