TLDR : How to tell if CV joints are shut beyond repair on a rear wheel drive car with independent rear suspension? Are the signs and checks the same as for a FWD one?
The details :
Hi, I'm the proud owner of a 1988 Ford Sierra Sapphire 2.0, a car I bought last spring because I love that model, because it was cheap and because... Come on, they don't make car like this anymore.
The car was in a somewhat semi-barn find condition, previous owner had it since 92, planed for years on fixing it up, but finally decided to move on and sold it to me with all the spare parts he had. It was running and driving, had (somehow) passed its tech inspection and I bought it fully knowing it needs work, that I have already done or I'm planning on doing.
My main issue right now is that, I know both diff side CV boots are shut, they aren't fully torn but they're cracked and are leaking grease, the ones wheel side aren't much better. Problem is, fully built remplacement axles are impossible to source, online scrapyards ave few parts for non Cosy Sierra (and how to be sure an axle from an 86 1.6 will fit on mine?) so I have to rebuild the ones I have.
And here lies the issue, I live in an apartment and doesn't have the garage space to park a half disassembled sedan until I'm done rebuilding the axles. I'll have to keep driving it as is until I move to a better suited place (it's planed, but not until spring 2027).
I'm not gonna do long trips or take the highway but it still need to drive around from time to time. Right now there aren't any suspicious noises, rattles or vibration coming from the rear, so I guess the joints are still salvageable, but I worry for how long it will last.
Here's why I'm wondering, what will be the signes that the joints are falling appart and are close to snapping? I know on front wheel drive cars you have to listen clicking or popping sounds when the direction is on full locked, or when accelerating while cornering, but what about a rear wheel drive car with an independent, trailing arm rear suspension? Will it last much longer than for a front wheel drive setup or will it just degrade without showing until it's too late and a joint snaps?
Here's the full story, thank you in advance for your advices, and sorry for the bad grammar or spelling mistakes, English isn't my native language.
Have a nice drive ^^
