purchasing motor mounts; bearings fail


Recommended Posts

Hello,

I need to get some motor mounts.

Ea82. Loyale 91 and for my 93......

Where is the best place (price)...

 

It eats wheel bearings... inner wheel bearings

fail at like 20,000 miles.... I am figuring it is the

motor mounts causing this....

Any thoughts......

 

And what about swapping with a 2.2

Thats EJ motors........

How expensive can that get....

Say you already have the motor for the swap..

use the search function above... and search for EJ SWAP.

 

Pop some popcorn and start reading, youll be there a while- LOTS of information to be had.

 

Youll definitely need an entire EJ22 donor vehicle to do a swap though. Just to get you started.

 

Also : Ive NEVER heard of motor mounts in any way causing wheel bearing failure.

Ummm, not likely that your engine mounts are causing the problem.

Chances are your hub has become warped and is distorted enough destroy

wheel bearings.

And hubs are usually cheap if you get them from a junkyard.

 

Its easy to check to see if the existing bearings are good, just wiggle the end of the axle shaft.

If they are still good then you should be ok to buy it.

 

Oh, and more than likely if it were mounts causing your issue, I would think

they would be the tranny mounts...

 

And as for an EJ swap, it is worthy swap, but it requires an adapter plate, a redrilled flywheel, a merged engine harness, and a lot of other miscellaneous stuff that is better explained in the retrofitting section.

 

As for cost of an EJ swap, it all depends on how much work you want to put into it.

If you do all the wiring yourself, already have the engine, do all the necessary mods yourself, and only buy the stuff the average mechanic can't make (the adapter plate, clutch kit etc) you'll probably be around $500 into it.

PS: Another hint, search for the info you need ;)

I have a 91 Loyale and a 93 both are wagons.

 

the 91 got new motor mounts when I redid the car.

that was about 5 years ago @ 158k. Now the car

has 262. so the motor mounts have about 110K on them.

 

Just recently the exhaust front pipe broke. I still

need to fix it... the welds cracked on both parts of

the pipe off the heads, where they are welded to the

cat. visually, the motor shakes when I rev it.

so the idea with bad motor mounts burning wheel

bearings is that when the motor is twisting constantly

back and forth, back and forth due to the motor mounts

this puts stress on the axles as they spin

which then places stress on the spinning wheel bearings.

Over time it prematurely wears the wheelbearings out...

If you drive straight down the road, the wheel bearing

is quite.... turn the wheel any slightest amount and

you hear the lovely grinding sound......

 

 

Some one mentioned possible bad hubs.....

can you describe a bad hub. how to determine a bad hub.

 

 

I replace bearings on the passengerside of the other car

the 93 and the inner bearing is toasted now.....

It is probably about 15k old.

I was even considering the possibility that they are

manufacturing these bearing poorly.... So I got some

dealer bearings.... It didn't make a difference......

I was even think that the grease is lame.............

but I have used this grease in other bearings(but those were tapered roller bearings)

 

really, I am changing wheel bearings more often that I change spark plugs.....

 

Any insight would be greatly appreciated...

If anything, the increased torquing from the motor due to bad mounts would damage the inner axle shaft joint, but I doubt the slight amount of extra twist will do them any harm since they are designed to flex in 360* while transmitting the power to the wheels.

 

The hubs can get out of round if the wheel bearings have been bad for awhile they distort the seat in the hub. If the hubs get distorted (out of round) then even if you put new bearings in, they will fail prematurely just like yours are doing because they aren't running true in their race.

 

Try some junkyard hubs or ask on here, somebody may have a pair for sale.

If the area on the outer cv joint where the inner wheel bearing seal rides is rough, it will let water into the bearings. Also, there are 2 styles of inner wheel bearing seal, the right one should have an extra lip that sticks out and rides further up on the cv joint that acts as a dust shield.

 

The spacer between the 2 bearings can get crushed, and will preload the bearings too much.

 

A deformed hub bore will do the same thing, the bearings won't be properly positioned and the preload will be wrong.

Ok so I can check for out of roundness of the

hub with an outside micrometer. And I should check both,

where the inner bearing presses in and the

outer bearing presses in...

What is the allowable amount of out of roundness.....

 

.003,.005 .007 .010

Not sure of the spec for roundness on a hub, you might want to start another post for that info as it will need to come from a factory service manual. Many people on The Board have that info but they might not be looking at this thread.

 

You won't be able to check the hub with an outside mic as it's the inner surface you're concerned with. If you have some telescope gauges to go along with that outside mic you might be able to get away with it, but again it will depend on the tolerance given in the FSM since telescope gauges aren't all that accurate for that kind of measuring.

 

Taking the hubs to a machine shop is really the ticket, but you could probably get a set of hubs from a JY for less then a minimum setup fee at a shop.
