axle wrap or something else?

i have a 2004 taco prerunner with the trd off road package. when ever i put it in reverse and pop the gasa little to hard i get pops and thumps that sound like they are coming from the front of the vehicle. could the noise becoming from the rear and sound like its from the front. not quite sure where to start with this one.

 

How many miles?

 

bought it 5 months ago at 97,000 its sitting at 120,000 miles right now.

 

Sounds like the u joints and slipper spline need to be greased on the driveshaft. Mine did that till I bought a grease gun and mobil 1 grease and filled all the zerk fittings until grease comes out of the u joints and the slipper shaft. Just my .02$

 

i will give that a shot cause i have like three grease guns laying around.
