My 02 Land Rover Freelander shakes when I accelerate. It is definately coming from the front.

The Freelander, along with all Land Rovers are permanently in 4 wheel drive: You need to take the car to a workshop to see what is happening. Freelanders have big problems with the transfer box, this maybe the problem. When you reverse the car and put the car steering to full lock whilst reversing, do you feel that the car is blocking or binding, as though you have the brakes on. If so this is an indication that the transfer box is faulty. These boxes cannot be repaired, replacement only and are quite expensive.
Hope this helps

Hydraulic lifters? I have been racking my brains for this one. Lifters will sometimes pump up when cold and then lose pressure as they get worked. Would explain why your camshaft died. Suggest you look at old camshaft, see the cams that were worn and replace those lifters. Only thing I can come up with!

how did the cam shaft failed? is there a spark on the plugs for the cylinders than are not firing? did you have a timing belt failour? if so you may have damage valves or pistons, do a compression test on the engine to know condition of cylinders
