OK so now I have changed my original 3.92 diff with 7.5 inch top beam for a 3.62 with a 7 inch beam allfitted and hub nuts tightened correctly. On the shorter nearside lobro shaft I have movement in the shaft (in and out) but no movement in the longer offside shaft. Is this normal? I have placed a jack under the offside wish bone and have full movement through the suspension cycle. A bit confused!!
