Outer Limits 4x4 Board

Hi, just aquired a 60 series as is, had a check done and all it requires is the play taken out of the l\h front . laying under the car, it appears the play is from the swivel bearings, confirmed by the w/shop guy. Now, how do I take out this play, appears to be a cuppla shims top and bottom. Can't get any help from the Toy w/shop in town. Another out of town tells me it is never usually a problem, being set new for the life of the vehicle. How do I figure out which shim I remove, top or bottom? Always had any work done in the proper w/shops in the past but a divorce and loss of regular work leaves the money tight

If the bearings were fitted from new they would be past their used by date, In that I mean that they will be surely worn and will need replacing.
Even though the bearings don't rotate alot whislt driving they do wear out due to brunelling (impacting movement between two surfaces)
A kit is available from most 4x4 shops to do this job which is a little time consuming, but possible to do at home if you are mechanically minded.
Do both sides whilst your at it because the other will be just as bad for sure!

As already mentioned.
Do both sides as a kit.

Just replace the bearings, and re use the shims that are already there, keep top and bottom shim pack seperate, and then check for correct drag once new bearings are in place.
98% of the time, they are spot on.
