Inner CV Joints
 

Can I use XR 4x4 ones? Any suggestions where I can get some from for a decent price?

dont know if it helps but you can buy the bearings for the inner front cv joints from woodford garage £50 each

you can use the bits from the sierra, the shafts are approx 1 inch longer and have been known to cause a few issues but the rest of it is a direct replacement
