How do you get a Suspension to hook, when the track surface is marginal at best

Dr Diff for $295?
yup that's where my axles came from. Bought then last year. look like there going it, This winter.

No i have never had a problem getting the axles in or out. but the last time i pull a axle in was 5 years ago.
they are the stock chry axes in there and when i put my 4.56 gears in i made a white paint mark all the way across the axles. Will be interesting to see how much the axle shafts have twisted up!
