Default Some General Car Questions

I got my first 4wd car a little while ago and I had some questions about things that were going wrong any help is appreciated.

1. CVDs, I cant get them to stay tight for anything I tried a little locktight, alot, none, but the pin just keeps coming out and ive had to buy replacements for them

2. Dirt in the Gears, dirt has been getting in the pinion and spur, im not sure if thats normal or not but I usually just let it run and clean it out after the battery is done.

3. The bottom screw of the shock pulls out of the a-arm somtimes, for example if i landed hard off a jump it might strip out and then i have to use a larger screw for the a-arm.

What 4wd do you have. Some cars have sealed drivetrains like the XX4. Other have open drivetrains like Yokomo MR4-BX. As far as CVD's I use Associated Locktight, never had any issues with the pins coming out.

HPI put out a little tutorial on how to "bulletproof" your CVDs:


Rather than putting Shoe Goo on the pins, I too prefer to put heatshrink instead. Works great on my B4 CVDs, which should be pretty similar to the ones on your BJ4.
