1998 GMC Suburban Repair Question
Mileage: 280,000 miles.
Clicking Noise
Answer
Soemtimes the heat shield for the front brakes touches the rotor and makes a noise. Take a look at it especially by the lower ball joint. Pull it away from the rotor but rmember a tug away here makes it closer elsewhere.
The other possibility is a failing axle.
I forgot to mention that it does this while sitting still and in neutral or park
That could be a failed lifter or a failed timing chain tensioner causing pinging or knocking. With the mileage you have a failed wrist pin on a connecting rod is possible.
A failed fuel injector can make a loud ticking noise
Take a screw driver and put it to defferent areas on motor, i.e.; near top end to see if you have a noisy lifter or near fuel injector to see if one is loudly ticking.
Let me know how it goes.
my code reader finally came in today I get a code p1345 (Camshaft to Crankshaft Position Correlation Fault)code this be causing the loud clicking noise
It is probably throwing the timing off enough to make it knock and/or detonate.
It needs to be replaced and if it is detonating, you should not drive it until it is fixed.
Let me know if you need anything else.
Thanks for your help I will look into that as soon as i can. and I will let you know how it turns out
You are very welcome. Come back anytime and I do want to know how it turns out.
