Changing out bearings in the front IFS

[wngrog]

I have some wobble from 45 mph to 70 mph on my 100. I thought it was the tires, but that was not it.

The tire store jacked with it and the hub bearings are loose on the front end.

In a solid axle it would be the top and bottom bearings because the slack is there if you grab the tire at 12:00 and 6:00.

Shaking at 9:00 and 3:00 it is tight.

I know exactly what to replace on a solid axle Cruiser for this slop, what needs to be changed on an IFS Cruiser? Any special tools needed?

A quick parts list would be very handy, but that may be asking too much

Same here

I just replaced the Dunlop Grandtrek tires with Michelin Cross Terrains and feel the same wobble from 45 to 70. Alignment and rotation didn't fix it. Maybe one more pass at road force matching and then it's going for a hub job.

Did they Road Force balance your tires? Do you know for a fact the front hub bearings are loose or just taking the mechanic at his word?

FYI: I just, apart of the ARB and 4.88 install just replaced the hub bearings on mine. I had a shop press the races in but other than that it is a pretty straight forward job...

I'm am also clueless on this IFS stuff so would love someone to make a video of this if they get around to it?

Yeah, I felt it myself. It is loose.

When you say hub bearing (as he did) that would indicate the bearings on the spindle, right? If those are worn you usually get slop at 9:00 and 3:00, not 12:00 and 6:00.

Kingpin berings on my D60 would give me the slop that I am feeling. Is there an equivilent on an IFS front?

Ball joints on the upper and lower suspension arms? That's about all I can think of as far as connection points at 12:00 and 6:00 for the IFS front end. If it's the ball joints, better replace them before they SNAP!

Man, IFS sucks...

I would adjust the wheel/hub bearings a little tighter to feel if the play goes away...sounds strange IMO (note: non-expert opinion) you would only have play in the wheel bearings at 12:00 and 6:00.

Wheel bearing slop is detectable at any tick of the clock, however if everything else has no slop, then you will feel it at 12.00 due to there being no other movement, as when you try to feel it at 9 and 3, there is some movement in steering that may take away from feeling the wheel bearing. The best way is to have someone under the vehicle watching when the wheel is worked by someone else, that way you can watch where the movement actually is. Then you may detect wheel bearing play, ball joint movement, control arm bushes movement, steering joint movement etc. The other thing to do is to tension up the wheel bearing to the required tension(figures in a recent post), then have another feel and see where your slop is. (Its still better looking from underneath I reckon). My humble thoughts only.

Yeah, first job should be to check the torque on the wheel bearings on the spindle and tighten them and grease them (if applicable)

Makes sence that the small amount of slop I have could be the bearings.
