Dear,
Next time buy a Honda, you won't have trouble like this.

Allah Akbar!

Might be a worn drive shaft linkage at the rear axle (differential). Could certainly be a worn wheel bearing.

Spider gears are not difficult to replace...however, if they are worn, usually this contaminates the lube and can cause damage to carrier as well as pinion bearings...Those require precise settings with special tools and lots of experience to replace. Since you have had the noise for a long time, I can safely assume that debris has been building all that time. Spider gear set is not cheap...You may want to risk doing the job, but I would likely find another exact match, drum to drum replacement in a scrapyard. Generally I will only recommend a spider gear replacement if you have snapped a gear in half...an immediate failure
does not generate the kind of fine metal that wear does.

What is your VIN number?

Clunking noise in the rear of the vehicle is a broad statement. When is the vehicle doing it? Is it all the time or just over bumps? Is it happening only going around curves? Is it a constant bump that speeds up and slows down with the vehicle speed. You would be supprised how many clunking noises can come from the driveline not the suspension. It could be anything from a bushing to your rear differential getting ready to grenade.

If your engine light came on, the engine module could have stored a code.
You need to have a scanner to check what code it is and that will point you toward the solution.
Possible causes could be (crank sensor, tps sensor or oxygen sensor).
Don't go replacing parts until you scan the vehicle for codes first.
