Can speedometer cable number D4AZ-17260-D be used on a 1979 4 x 4?

 

Incorrect, D4AZ17260D is for a 1974/78 LTD/Mercury Marquis w/o speed control.

You need to be more specific when asking this question.

What 1979 4WD do you have, F150, F250 or F350 (or a Bronco)? Is it an A/T or a M/T? Does it have part time drive or full time drive?

There are FOUR different speedo cables listed for 1979 F100/350 4WD's.

What's wrong with the cable you have now?

btw: The speedometer driven gear on the end of the cable does not come with it.

 

typing too fast. it is D4TZ-17260-D

for a 1977 not 79 F-150 4x4 400 cu in V-8, Auto Tranny C-6
Part time 4WD

 

The following is the cable you need, D4TZ17260D is in-correct (see below).

D7TZ17260J .. Speedometer Cable -82" long / Use with 4WD & C6 and NP435 and Warner T-18 4 speeds / Obsolete

D7TZ17260J replaced D3TZ17260H / Fits: 1973/79 F100/250 4WD & 1979 F350 4WD all with Part Time 4WD.

No Ford Dealer or obsolete parts vendor has D7TZ17260J.

D3TZ17260H = WESLEY OBSOLETE PARTS in Liberty KY has ONE: 606-787-5293 / GREEN SALES CO. in Cincinnati OH has ONE: 800-543-4959.

No Ford Dealer, no other obsolete parts vendor has any.

Do you really need a new cable?

You didn't answer my question of what is wrong with your old speedometer cable.

Inside the cable's outer housing is a woven steel core which is supposed to be lubed every so often with a thin film of white lithium grease.

What happens: The lube dries out, the woven steel core binds up inside the housing and snaps into two pieces.

EVERY autoparts store sells a "universal" woven steel core kit. You cut it to length, lube it and install it in the housing.

Thanks for the information and advice!

 

Autozone had an assembled cable for my truck for $20. No cutting to size at all. I would give them a call.
