Hey everybody, first post. Been checking out the sight regularly, though. I have a question about 3rd gen 4runners. I have a '96 SR5, with stock coils (Toyota replacements in the rear) and original struts in the front and Monroe Reflex shocks in the rear. I recently did a lot of high speed driving on some rough forest service roads and I found that the truck has a scary tendency to have the ass end shift over to the right out of the blue, which I find to be a bit of a problem to say the least. Is this a common problem with the 4runners? Is my only answer to just slow down, or does anybody have some advice as to how I can fix this? Would new struts up front help this? I have a set of OME 890 coils, but I don't really want to raise the center of gravity on the truck, as I think this would probably aggravate the problem. Any advice is appreciated. Thanks in advance.

 

Mine does that too, and I have 88K miles, bilsteins, and new coils (at 67K miles). My Tacoma also did this at 30K miles. It is the nature of a solid axle.

Were you aired down a little? If not, try airing down a bit, as it seems to help alleviate some rear end wandering.

 

Wow, thanks for the quick response. Yeah, I have 31 X 12.50 XTerrains on it and normally I run them at around 40 psi on the street, and they were dropped to about 30 psi last week. For rougher stuff I would drop to about 20psi. Do you think that I should run them lower on the forest service roads?

 

I usually run around 25psi on washboard desert roads if I can help it. My rear still kicks out at times.

 

I guess slowing down is probably the answer. That's definately the cheapest option, anyway. I'll try airing down a bit more next time. It seems that the coils with solid axle setup is sketchier than my pickups that I have had in the past. If it was more predictable, I could alter my driving style, but it just jumps over sometimes. Sure gets the heart-rate up, when you have big drops over that side!
