Hi, when i'm coming off the third and the second gear mainly the 2nd gear it makes a clanking noise


My first thought here is your drive shaft u joints, but only because I've been stranded more than once by these. The higher torque of second will definitely make a worn u-joint "clunk". with the window down listen carefully as you engage and release your clutch in 1st gear, if you here any "clunking" noise I would check your u-joints. To do this SAFELY;ie, using jack stand etc. get under your car and try to turn the drive shaft by hand with the car in gear. ANY play in the drive shaft is bad. I'm not sure if you meant you've changed your clutch and the pressure plate or you did change out you flywheel. either way whichever you did not change could definitely be warped.

My chevy truck is making a clonking noise in the rear end either wheel or im thinking drive shaft when i hit the gas on take off and while im doing like 50 mph what is it


drive shaft u-joints will make clanking sound putting in gear or have bad vibration to it . it can be pion bearing in rear-end it will do what you are saying . but check driveshaft , sometimes you can see if drive shaft has play in it move side to side .

Clanking sounds when i back up and put it in drive also when i turn corners


Get your differential fluid checked and make sure you get synthetic for the rear if indicated. The clanking on turns reduces the possibility of the U-joints being the culprit. The driveshaft would give you noise going from reverse to drive, but in turns it is likely the clutches in the rear axle.

A four wheel drive can cause noise in all directions if the front drive has bad joints.

I have a 99 tahoe 4X4 4 dr. that has a drive line clunking problem when I start and stop, seems to be coming from rear of vehicle and getting worse........HELP Please...


It may be a u-joint, check that.If the driveshaft moves back and forth due to worn u-joints, replace both of them. Also the splines going into transmission on driveshaft tend to form a groove causing it to 'clank' upon starting/stopping. Chevy offers a nickel-plated yoke to replace the offending part. Do not plate yours as it will not fit after. If you don't replace it, you can grease it and the problem will go away for a while till the grease wears thin and the noise returns. If that's the case it's a very common problem you can find it and the solution easily all over the internet. I suspect it will be u-joints or notched yoke. Lastly, it may be a rear-end that needs the lash adjusted. On my truck the sound is a clank that doesn't sound horrible just annoying and a little worrisome till I knew what it was. The GM clank baby, been around for years. If it is u-joints you'd be getting vibration at speed that gets worse and worse till it's unbearable.

I changed my front right cv joint and now the clanking/grinding wound is worse and my bakes arent working but there is enough fluid


The CV joint has nothing to do with the brakes you probably put something back wrong because you had to remove the Caliper and Brake pads.
The CV joint you probably never replaced the C clip which keeps the shaft spline from going out into the hub. The CV joint also has to be synchronized. Which means they have to line up on both sides. Most will mark the shaft first, before removing.

Clanking like sound in the front end that sounds like either the drive shaft or the gears in the transfer case? Hard to hear unless pulling in the garage where the sound bonces off the walls. The clank...


First of all you need to be more specific-- Is this a car, truck,or whatever. Is it front wheel drive? Is it four wheel drive? (Sounds like a four wheel drive) Basically we need to know exactly what type of vehicle you have. As far as the noise you hear, it could be any number of things-- such as bearings. cv joints, universal joints, and so on. Once we know what vehicle you have It will definately help us narrow down the problem. Ed

Dodge ram 1500 5.9 1999 Clank at the start or reverse or drive.


Sounds more like a universal joint. Should be a inexpensive fix have it checked soon or you will need to add the price of a tow to the repair bill. part should not be over $30 each x 2 labor should not be much more than an hour.
