Question about 1999 Chevrolet Silverado 1500

1 Answer



I was driving along today in 4wd when I heard a very loud clunk. The trk. seemed fine until i tried to go in reverse. I can shirt it into reverse, but it won't go.
It drives forward in all gears fine with no strange sounds.

the truck has been very well maintained all of the years that I've had it.

Thank you in advance for your help.

As far as not having reverse onthe truck anymore could be one obvious to many litlte things really..but I believe that your back axle probably has about $1200 in repairs coming.

In 4 wheel drive the front will pull the truck along but has nothing to do with going backwards.....I hope you understnad what I mean.

If the Pumpkin hasn't been maintained by checeking an chaging the lubricants you may have destroyed a gear, or gears that make the back axle do it's job.

The cheapest, but best thing to so is have a GM garage replace the bad gear/s, and seals as long as they have it apart.

Without actually hearing your vehicle, or feeling what it's doing. ... it's the best I can do for you.

Happy Holidays

Heard a clunk while driving diesel ford excursion now when drive and reverse don't work....any ideas what problem is?

If it is a four wheel drive check your tail shaft or drive line by securing the vehicles front wheels jack up the rear tires and in park try to rotate the drive line if you can hear the transmission sound like it is going into gear the transfer case could be damaged! If not a four wheel drive pull the transmission dipstick and look to see if the fluid is dark red or metallic grayish color if so then you're clutch disks inside the tyranny have been worn out and it needs to be rebuilt!

If you have automatic free wheeling hubs then they are not engaging correctly. They may need attention and/or adjustment. If you have hubs that are required to be physically locked in then check that the engagement is complete when turning the lock nut.

Transmission made a loud pop then quit moving in drive. Truck still moves in reverse

An automatic transmission consists of a series of bands (gears) which is each gear within the transmission. You state that truck will move in reverse, but not in drive. The loud pop you heard was the forward gear band breaking. From this point you have two options...either have the transmission rebuilt or replaced.

98 Jimmy 4WD clunk

It seems like no one else hear at FixYa is responding yet to both your requests about clunking in 4wd.
I see two the first a 2000 blazer from Gloeckz
there is a rapid clunking in 4wd!
In the second it clunks hard going in then won't drive!
This is rayenc11s' 98 Jimmy 4WD clunk I'm no trans specialist and not familiar with repairing or troubleshooting serious 4wd problems but it sounds like this may be a problem in the transfer case.

Since no one seems to be helping you but me I'd suggest you go to a transmission shop and ask them if this is a common problem that may lead to a bad transfer case if not corrected!

Make sure you have the proper fluid in your transmission case, transfer case and differential case first or have a quick oil change place check it for you!

Hope this is helpful.

Good Luck!
