Son has been running the avalanche the last few days and has had problems with steering every day. Seems like steering goes to full lock and wont unlock unless I force it. The servo broke and one time when steering locked it bent a front axle and broke a wheel off. Steering is VERY wide to say the least. I have tried to fix steering but it looks like when suspension is compressed and turning hard the turnbuckle gets stuck on the lower a arm. It will do it both ways. I have done adjustments and nothing will work. Im getting very frustrated. Anyone have any suggestions before I burn it. Now I have a broken wheel, bent axle and bad servo. We have had it since christmas and only put 3 tanks through it. [:@][:@][:@] Oh also I still dont have the parts for the leaky shocks that was supposed to be sent a couple weeks ago. Im not happy right now.

I was having a similar problem with my st-1, All I did was replace the steering servo with a higher torque model and it corrected the issue. I realize that might not be your problem, but if it were me thats where i would start. Check the saver aswell, if you havent made a parts order yet i would get one of those. Sometimes they will cause these issues. If I think of anything else Ill stop by and share it with you.

that only happens to me when i take a big jump and hit on the front wheel, it has to hit pretty hard too to have it happen, i just move it back and run again.

I have already replaced the servo. He has taken jumps but it has happened when he is at wide open throttle on a bumpy turn but the last time the wheele locked up ont he chassis, broke wheel and bent axle. Do these not turn very well? Are the tires too big for this truck so thats why they get jammed up? Why does the Monsoon not do this? I am very happy with its performance but the steering is really bad.

i am happy with the way it turns, i only have the steering problem locking up when i hit a jump and land on one of the front wheels.

Monsoon has longer arms wich alleviates the wheel jamm up. I ordered hub extenders on mine and replaced the servos with Hitec HS 645-MG.

Avalanche already has hub extended hubs. How many oz is the 645mg?

No matter what truck you buy, you always have to replace the steering servos with better ones. My t-maxx's were the same and my Savage also! I decided to buy metal geared servos and have never run into a problem since.

Ok I fixed the steering problem. Me being a mechanic I disected the whole steering to understand how it works exactly. Come to find out that if you dont have enough toe in it will lock up on a hard turn or if you land wrong on a jump. I only had one side locking up so I had to figure out why one side locked up and not the other. The side that had some toe in is the one that did not lock up. The other side had no toe at all . Now here is how tofigure out the toe if you are having this problem.

Put the front of the truck up and let the suspension droop. Turn wheels all the way to one side. Now look at the outer steering turnbuckle and see how close it is to the a arm. You should have at least 1/8 of an inch of space between the turnbuckle end and a arm. If steering end hits the a arm you dont have enough toe in. Just turn the turnbuckle out till you have about 1/8 inch of space. Now turn steering to the other side and repeat. Having the toe in will extend the turnbuckle and prevent it from folding in and getting jammed on top of the a arm. You can fool around with the turnbuckle to see what I am talking about. If you put negitive toe and turn the steering you can turn the tire to full lock and it will get jammed on the a arm. At full lock the steering end should not touch the a arm when suspension is at full droop.

BTW the stock servos are metal.

rc_crazy21

Well it good to know they are metal geared, but still invest in a good strong Hitech servo.

twomanytoys

Oh yah I know.

Syclone354

I had this same problem, ill have to check mine out.

twomanytoys

change the toe and it will fix it.

Glad it worked out Twomany, and thanks again for more insight on the truck!

twomanytoys

No problem! HAs it happened to you also?

Defmeq

Nope, mine turns pretty good. Believe it or not i run the steering servo that redcat sent me after the original burned out right away. I bought the hitec servo for the steering but after the brakes problem i thought to switch them and havent changed it since. I was suprised to see that the redcat servo worked pretty good and has continued to for countless tanks of gas.
