Thump noise in front end

Thump + hiss, moving, is a very bad sign.
why not get the car inspected by an ASE tech, mech.
?????
we can not do noise here. only real ears, (in stereo) work.
and lots of other checks.
get is serviced , it might not be safe to drive it.
or is about ready to have a cascade failure.

I tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my ford explorer. it wont move forward
or reverse, engine is good both solenoids for forward and reverse work.
I don't have much technical knowledge but I just followed it step-wise, and works perfect! got it from www.reliable-store.com

sounds like wheel bearings-1st
but hopefully your front disc need turning, or replaced.
check wheel bearings by jacking up the front end "CAREFULLY" WITH
JACK STANDS & wiggle tires,if you get more than a 1/4'' slack on 1 or the other, than it's shot. Best to replace both sides. "GOOD LUCK'' &
BE CAREFULL.

My thought would be to look at the u joints and drive line. When driving the car and it makes the thumbing sound shift to natural, if the sound stops it is probably in drive line.

sounds like ball joints raise front end up check al conections in relation to front end .

It all depends on when you are hearing it. Does it do it all the time, anytime the vehicle is moving? Does the noise speed up and slow down with vehicle speed? Does it do it only when hitting bumps? Does it do it when you are making turns?

Any part of the steering and front suspension could be the source of your noise. Much more information is needed to tell you what the probable cause is.

Give me some more information about this problem. May be i can help.

This would be your front struts.

yes my cv axles had to be replace cause of the same thing but when you replace one side you need to do the other side at the same time cause when 1 goes bad the other is not that far behind . i know from experience

sounds like you need your transfer case looked at and repaired.....that the only thing i can think of...hope it helps :)
