Who has the oldest Avalanche with lots of run time on it. I just bought one for my son and I want to know if there is anything I need to worry about wearing out or going bad in the long run. Besides the obvious. It looks to be built very well. I had problems with tire foams on our Tsunami. Will this be a problem. Anything with steering, bearings, a arms etc or has it been totally relaible. Anything that needs to be upgraded. Opening the box I saw oil all over inside and to find out that I have 2 shocks that leak. 1 rear and 1 front. I hope this is not the start of the problems. I installed 60wt shock oil and adjusted the suspension. From about 3-4ft up I can drop it and it will not bottom out but yet its still soft. I have to get 2 shocks replaced. I fixed the exhaust problem with it rubbing the fuel tank, tightened all the screwes and used locktite where I thought it should be used. I still need to cut holes in the body for engine and air. To me it looks very tough. Better than alot of monster trucks that I have seen. Definately better than my TMaxx. Again I just need long term reliability, upgrades and possible problem info.
