The mixture of molten rock, crystals and dissolved gases from the mantle is called magma. When magma erupts to the Earth's surface, it is called lava. Not all volcanic eruptions happen near the boundaries of tectonic plates. Some eruptions happen in the middle of the plates.These eruptions are caused by mantle streams called plumes. Mantle plumes are formed when hot magma rises beneath the thinner, or weaker, areas of the Earth's crust, creating 'hot spots'. Volcanic islands are formed when mantle plumes form at the bottom of the ocean.ome eruptions happen in the middle of the plates. These eruptions are caused by mantle streams called plumes.

Burst Fracture of the Lumbar Spine. General Considerations. Burst fractures result from axial loading most often secondary to motor vehicle accidents and falls. The axial load drives the intervertebral disk into vertebral body below. Usually produces a comminuted, vertical fracture through the vertebral body.
I think you guys named just about every moving part connected to the rear...That really narroweded it down for him...lol. Normally look to the carrier or pinion bearing. Biggest cause of a failed pinion bearing is the NUT backs off the yoke. which in turn makes the pinion loose changing the preload which prematurely wears the pinion bearings. LOW fluid level will be the next biggest culprit of bearing failure. Good luck on the search for your HOWL. Jim :thumbup:
