2nd Gen 4Runner Interior Restoration: Cracked Dash, Seats & Headliner
The cracked dash
Almost every surviving 2nd gen has a cracked dashboard. Three decades of sun turns the vinyl brittle, and once the first crack opens it spreads. It is the single most common interior complaint on the platform.
Your options, in ascending order of effort: a custom-fit dash mat, which covers the damage completely and kills windshield glare in the same move; a dash cap that bonds over the original; or a full dash replacement, which means pulling the entire assembly and is a weekend project with a lot of small fasteners.
For most owners the mat is the right answer — it takes ten minutes, it stops UV from making the cracking worse, and it costs a fraction of the alternatives.
Sagging headliner
The foam backing on the headliner board disintegrates with age and the fabric drops. Tacking it up or using pins is a temporary fix that looks like a temporary fix.
The proper repair is to drop the headliner board, scrape off every trace of old foam, and glue new headliner fabric with high-temperature adhesive. The scraping is the tedious part and skipping it is why re-done headliners fail again.
Do it on a warm dry day and give the adhesive time. This is genuinely a DIY job and the results are dramatic — a clean headliner makes an old interior feel decades newer.
Seats, plastics, and the small stuff
Driver's seat bolsters wear through first. Seat covers are the practical answer; upholstery work is the correct one if the foam underneath has collapsed. Check the seat rails and mounting points for rust while you have things apart.
Faded and chalky interior plastics respond well to a proper trim restorer rather than a greasy shine product. Clean thoroughly first — most products fail because they were applied over thirty years of film.
Fix the rattles while you are in there. Most 2nd gen interior noise comes from loose door cards, a dry rear window mechanism, and trim clips that have gone brittle. New clips cost almost nothing.
And if your rear tailgate window is misbehaving rather than just rattling, that is a known platform issue with a known diagnosis order — our tailgate window guide covers it.
