Just replaced CVs, any precautions to take?

[xxaarraa]

After 130k, I decided to preventatively replace the CVs even though I have no signs of clicking/noise.

Truck is lifted 3-4 inches (OME 885 + Bilstein 5100 + Toytec top out spacer). Diff drop. LR UCAs. 34 inch wheel/tire setup. Here's an old photo of the angle of CV.

Went with stock Toyota CVs again. Which means the boot is likely to spit grease and leak again.

Are there any precautions I should take now while they are still new? Replace the bands with newer rounded hose clamps?

What do you guys recommend?

Good photos! Ever since it was told to me that CV Joints are one of the weakest links in suspension - I sort of gave the fact to God that they're going to break with the lift.

So you bought new Toyota OEM drive axles or just the boots?

I would recommend replacing seals at the diff and possibly the inner seals at the hub, where the outer cv touches. I use synthetic oil in my diffs, might be a good time to drain her out at 130k

I too have used synthetic since I bought the truck, and replaced diff fluids every 20k religiously, not worried about that. Thanks for tip about replacing seals, I will look into that.

I was asking if there are any precautions one could take while the CV and their boots were still new. When a truck is lifted, the stock CVs spit grease from the inner boot, but since I have 34' tires on, my CV angles should in theory be 'better' and closer to stock than with smaller wheel/tires where the suspension lift causes a steep angle.

Any thoughts on that?

They must make a longer boot?

I don't think the CV angles are effected by tire size, just lift amount (coilover preload or spring geometry).

CVJ has different boot materials and maybe sizes too on their remanufactured CVs. Otherwise just look into a different boot clamp.

This makes absolutely no sense. The size of your tires have zero effect on the angle of the CV's.

Thanks, will look into different boot clamps.

Interesting you guys feel that tire size doesn't affect CV angle. I know suspension lift changes the angle, no questions there. However, wouldn't increased diameter of the wheel change the LCA angle, thereby changing the CV angle? Said another way, for the same amount of lift, a truck that's running 31" tires will have different CV angles than the same truck with the same suspension lift that's running 34" tires? Or am I smoking dope?

You're smoking dope. Its just geometry. The suspension lift can change the CV angle due to the length of the strut changing. This moves the LCA down, the CV axle bolts through the steering arm...which is bolted to the LCA, hence changing the angle. Tire size is outside of this and has no effect on the angles within the suspension. The CV axle goes through the center of the tire no matter what size the diameter is....so no change in angles.


And just hose clamp the boots and be done with them. I just re-did my drivers side CV last weekend.

Remove the stock clamps and replace with hose clamps?

I rebooted my stock CVs last year (that I just replaced) with an aftermarket universal boot, and used just hose clamps back then. That reboot job held up well so I may use the same clamps.
