Did you read your question?

How would someone know what is wrong with your truck?

You need the vehicle to test,don't you?

98 Honda crv transmission between 20-45 mph let up on the gas and accelerate there is a rumble, bank clank noise if I dtep harder it stops what is the cause


It is more than likely some of the bearings in the transmission are worn, when you step on the gas it puts pressure on the bearings thus noise stops but it will get worse and eventually collapse get repaired now to avoid further damage. Topsi

2001 cherokee 4.0 idles fine but once in gear with not accelerate and backfires in intake


Is there a metallic noise (clanking) when you put it into gear?? You may have a crankshaft sensor or crankshaft wiring that is causing problems. Check to see if there is any wires on the exhaust manifold or the exhaust system anywhere.

Whining noise


would need head under the bonnet to know for sure but feel the AC lines as a lack of gas can cause a noise like this but its not often that you can hear it above the clanking of the diesel engine ,no petrol ones here at our fuel prices

89 Bronco II 4x4, 6 cyl., chirps and clanks (badly) upon acceleration (clanking especially bad in 4x4 low) sounds like something is going to fall off. The clanking was minimal at first and has become...


Accelleration noises of the magnitude you descibe makes me think the engines crank shaft bearings have gone. Has the oil pressure light come on recently and what's the oil level like.
Without being there to hear it, it's very difficult to diagnose. You should detect noises and rattle if you rev it when in neutral if it is the engine. If the engine is smooth in neutral and the oil is good you may have a bad diff or cv joint

Clanking noise coming from Allison Transmission on a 2001 Chrevrolet Silverado 8.1 Liter engine


this does sound like theres a loose line tapping the engine/frame,during warm up the engine idles faster which could make it vibrate faster causing the the clanking or tapping noise,if this has started after trans fluid change,then check the lines running from the trani to radiator sometimes the service person might bang into something causing plastic clips that hold the lines to break,try getting under it and have someone start the truck and listen to see where it's coming from also hold the lines & see if the noise stops,the service guy could have unbolted something & never put the bolt back causing the clank ex.line may have a clip holding it thats bolted to the trani pan ?good luck

When I accelerate or decelerate I hear a clanking noise like chains on metal, I think it is coming from my transfer case. We just completed a cross country move towing our u-haul w/it. Our mechanic friend...


I would worry

Pull the transfer case & take it a part

You most likely will find the chain is loose
& wearing away the case from inside,that is
pretty much what your saying.

Don't install someone else's used junk from
a salvage yard,that is what the pros will suggest,
fix yours.

Oil light goes on and off


That's really bad ... First of all check oil level when its cold... The clanking sounds are your valves running dry. This will cause massive damage the heads. If you oil is low fill it back up & check the engine for leaks & hope there is not valve damage. If the oil was low and you filled it & you still get the clanking noise the valves are permanently damaged & the head/heads & valves will need to be replaced.. Big costs

98 ford mustang shift stick started making a clanking sound yesterday when backing up


If it makes a clanking sound when you switch from neutral to drive or neural to reverse than i would say you have a u-joint issue. If it you get noise when you accelerate and coast then your rear differential is out of alignment

83 vw rabbit gti clanking/knocking sound


That doesnt sound good. Check the engine oil level and top up as necessary. If the noise is still there, then you should take it to a mechanic to check. It could mean that you need to either replace the engine or overhaul it. Hope that helps
