My 89 Cherokee 4dr 4wd had new Goodyear MTR's in the rear, and old toyo
800's up front when I got it. There was a SLIGHT ocsciallting shaking felt
in the cab, (the steering wheel did not shake) at speeds of 60+mph. Braking
was straight.

I switched the Toyo's to the rear and the GY's to the front to attempt to
diagnose the problem. The shaking changed, and could then be felt more at
the rear of the vehicle. The Toyo's were well worn and did not match the
GY's in terms of tread pattern, so I decided to replace them, hoping they
were not good and would solve the shaking problem.

I had Les Schwab put two Dean "Grabber" tires on the rear. Same size as the
GY's (215/75R15) All 4 tires were balanced, and 20 new lug nuts were added
as the old ones had lost all thier caps.

Then, with the GY's up front the Deans in the rear, there was a bad shaking
in the steering wheel as well as the rest of the Jeep at 45+ mph.

I stopped at another Les Schwab about 15 miles from the original, and had
the balance on all 4 tires checked. The rears were "out of balance" and were
re-balanced free of charge. The shaking is still present at 45+mph, is
better than after I got the new tires but is WORSE than before I changed
anything to begin with. The truck also pulls right when braking now.

The manager at the original Les Schwab (A very nice guy), said that he
suspects my driveshaft is the problem, the new tires have nothing to do with
the brake problem. I don't understand how if it was a suspension problem, it
would be exaggerated by new tires? Could the old tires have been
compensating for this somehow?

The Jeep goes back to the original Les Schwab tomorrow to have the front and
rear suspension checked out, as well as the drivelines checked out.

Any and all opinions/advice welcomed.

 

I forgot to mention that it does not change with variation in engine speed,
and happens when cruzing, seems to get better or vanish when accelerating.

thanks,

carl

You are describing a bad u-joint on a totally illegal (in Canada anyway)
Cherokee. It has 2 u-joints on the back driveshaft, 3 on the front
driveshaft and one behind each front wheel.

Just a heads up for you. If you get in an accident that is bad enough
to have the police come to and they inspect the vehicle, 'You' will be
found 'at fault' in the accident because you have mis matched tires on a
4x4.

No if's, and's, but's or maybe's.

If someone is injured or dies, this can turn an 'accident' into
vehicular homicide.

I have been there and was told this by the police that inspected my
Cherokee and by my insurance company. Mine passed and the other person
was found 'at fault'.

Hey Mike, can you dig up something to back up your claim on mis-matched
tires? It seems to me that manufacturers wouldn't be able to equip vehicles
with space saver spares if this was the case.
