Question

my brother has a Eagle Talon and it has been having problems and i think it crankwalk because talon have that problems but i what to know what is crankwalk

and can you fix it

i put it under Mitsubishi because there like same

Answer 1

Crank walk is excessive side to side movement of the crank shaft due to worn line bearings or a worn crankshaft, this prbably means the crank bearings need to be replaced , drain the oil, remove the oil pan then remove the bearing caps take out the original bearings, replace them, you should be able to get them at Autozone or UAP, you also have to get plastiguage to check your bearing clearances, the instructions should be included if there is still too much bearing clearance with new bearings you have to repalce the crankshaft if you're putting in a new crank I would recommend new bearings anyways you still should check the bearing clearance and file the bearings to the right clearance if they do not provide enough clearance,
that's all there is to it so all thats left is to GIT R' DONE :)

Movement of the crank out of stock specifications. All cranks have L to R movement, to some extent, but an excessive lateral crank movement has bad reprocussions, such as hitting/grinding/destroying the crank sensor. A "walking" crank necessitates an engine rebuild.

Any car can crankwalk, but Mitsubishi Eclipses, Plymouth Lasers, and Eagle Talons with a 7-bolt motor are notorious for this problem. No recall was ever released as the problem was said to be isolated to a bad batch of cranks, which represented a fraction of the produced cars. Various theories of why crankwalk occurs and what years are most suseptible exist, but none are proven. General consenus is poor oil flow is one cause, and later model years seem to suffer less.

Contrary to popular opinion, any car can crankwalk; Manual, auto, import, domestic, turbo, manual, racecar, beater. All have walked, and all have a chance of walking.

There is a thing call a thrust bearing that is part of the main bearings that holds the crankshaft on "end to end" play. When this particular portion of the main bearing is damaged you can [with the motor OFF] pry the crank "in and out" without using much force. You have just tested the limits of crank-walk; which should be measured in the thousands but by the time it is noticeable it usually is visible by the necked eye.

Answer 4

in a nutshell, crankwalk is the amount of movement the crankshaft makes front to rear of the engine. it is controlled by one of your main (crankshaft) bearings called a thrust bearing. these cars had an especially bad problem with this allthough all cars can develop this condition. the aftermarket replacement thrust bearings didn't seem to have this problem. if you replace the crankshaft and bearings or maybe have it turned by a machine shop and put undersize bearings it will fix the problem.
